It was found that the yellow stingray can be trained to use magnetic polarity as a positive stimulus to solve a T-maze task, then it can relearn the task when the reward contingency is reversed.

However, the magnetic field is not stable, and at irregular intervals at an average of every 200,000 years polarity reversals happen. This means that the magnetic North and South poles swap places.

Earth's magnetic field is not stable, and polarity reversals where the North and South poles flip has happened on average roughly every 200,000 years. During the past 180 years, Earth's magnetic ...

Earth's Magnetic Polarity Can Flip Much More Quickly Than Previously Thought Published Aug 20, 2018 at 3:00 PM EDT Updated Aug 20, 2018 at 6:35 PM EDT By Katherine Hignett ...

The sun’s magnetic poles flip every 11 years, and scientists predict it will happen again in 2024. This could cause intense solar storms, disrupted satellite communication and more intense auroras.

SANTA CRUZ, CA -- Push two magnets together and you'll set off an avalanche of activity, forcing atoms on each magnet to align their polarity with the intruding magnetic field.

By controlling this state, researchers can enable the development of smarter, reconfigurable, and energy-efficient devices ...
