  1. Sea Turtles Find Their Birthplace with Magnetic Fields

    Sea Turtles Find Their Birthplace with Magnetic Fields
    Previous studies have shown that sea turtles use Earth’s magnetic field to help guide them at sea, similar to how sailors use latitude and longitude. Loggerhead turtles, in particular, have been known to swim thousands of miles to lay their eggs on Florida’s Gulf, as well as Atlantic coasts. What’s interesting is that recent research has found that these nesting places are actually within about 40-50 miles of where the turtles were born decades earlier.  Continue reading →
  2. Explaining Magnet Usage in the Netflix Original Stranger Things

    Explaining Magnet Usage in the Netflix Original Stranger Things
    Spoilers ahead if you haven’t finished watching Season 3 of Stranger Things! When a television show makes science references, they can either go over our heads or have us thinking “is that really true?”    We wrote a previous article about magnetic properties being discussed in the show: when the characters noticed things were going wrong, something “strange” was happening with their compass -- the needle was no longer pointing true North (though, it should be pointed to magnetic North). In this particular episode, they did an experiment and found that all of the compasses were deviating from pointing north, showing a very strong magnetic interference going on. We decided, for the most part, this event could be “real.”  Continue reading →
  3. The University of Iowa Wins a Record Grant to Study Magnetic Fields

    The University of Iowa Wins a Record Grant to Study Magnetic Fields
    There have been exciting things happening in magnetism. NASA recently awarded the University of Iowa (UI) a significant grant—$115 million—to study the interactions between the Earth and Sun’s magnetic fields. The TRACERS (Tandem Reconnection and Cusp Electrodynamics Reconnaissance Satellites) project, the largest research project in the university’s history, will be part of NASA’s Explorers Program.  Why Study the Magnetic Fields...

    Tate Features Pioneering Greek Sculptor’s Magnetic Work
    Greek sculptor Takis -- born Panayuitis Vassilakis -- is a nonagenarian (a person who is between 90 to 99 years old!) and is the subject of an art exhibition opening on July 3 at Tate Modern in London. Why are we sharing this?  His work is about magnetism!  About Takis Works Takis was an avant-garde artist of the ‘50s and...
  5. This Superconducting Magnet Just Broke The Strongest Magnetic Field Record

    This Superconducting Magnet Just Broke The Strongest Magnetic Field Record
    A new superconducting magnet, created by National High Magnetic Field Laboratory (MagLab) at Florida State University, has briefly sustained a record-breaking 45.5-tesla magnetic field intensity. MagLab also produced the world’s previous strongest continuous field intensity, which held the top spot at 45-tesla since 1999.  To put this into perspective, the magnetic field intensity of a standard fridge magnet is about...
  6. How the Moon Got "Sunburns" - Solar Wind and Magnetic Fields

    How the Moon Got "Sunburns" - Solar Wind and Magnetic Fields
    As we all know, the Sun is powerful. So powerful that any object, person, or planet traveling through space is susceptible to the Sun’s damaging radiation. The latest victim to feel the Sun’s fiery wrath? Earth’s Moon. Researchers, using data from NASA’s ARTEMIS mission, have reported finding “distinctive patterns of darker and lighter swirls” on the Moon’s surface. When looking into it further, they have found that these swirls may actually be “sunburns.” Should we be worried about these sunburns on Earth? Continue reading →
  7. People Can Sense Earth’s Magnetic Field

    People Can Sense Earth’s Magnetic Field
    A new study, published online in eNeuro, determined that through studying brain waves, humans can potentially have magnetoreception abilities. This “sixth sense” was previously only known to occur in certain animal species, such as birds and fish, who use the magnetism for navigation. What is Magnetoreception? While it sounds complicated, magnetoreception is, at its fundamental level, the perception of a geomagnetic...
  8. Is Earth’s Magnetic Field Flipping?

    Is Earth’s Magnetic Field Flipping?
    According to Nature, Earth’s north magnetic pole is moving so quickly that the World Magnetic Model (WMM) needed to be updated only four years after its latest update.  Even though the 2015 update to the model was expected to remain valid until 2020, it’s close to exceeding the acceptable limit for navigational errors. so, updates were made and released in February 2019. Periodically, the north and south poles move so much that they trade locations, which is known as a magnetic field flip.This phenomenon most likely should not occur for thousands of years, however. But, the fact that WMM needed to be updated so quickly has us questioning what is it that causes the poles to shift, and what this means for Earth’s magnetic field. Below, we outline what all plays into the changes. Continue reading →
  9. Magnetic Field Diode

    Magnetic Field Diode
    The future of electronics may change, as researchers have created a material that acts as a magnetic diode. This “magnetic field diode” is similar to the already known electrical diode, but this device could transfer a magnetic field to another object, but not the other way around. Continue reading →
  10. Jupiter's Moon's Magnetic Field

    Jupiter's Moon's Magnetic Field
    In December 1996, Dr. Margaret Kivelson, professor emerita of space physics at the University of California, Los Angeles, and her team of physicists discovered that Europa—one of Jupiter’s moons—had a magnetic field. Flash forward to today where Dr. Kivelson is now a co-investigator working on an instrument that will be used for the Europa Clipper mission. This spacecraft, scheduled to launch around 2022, will study the habitability of Europa, Jupiter’s “ocean moon.” Continue reading →
