Using an XMC1100 microcontroller development board and a TLV49 3D magnetic sensor, the device is able to track the poles of a magnet in real-time and produce an approximation of what the field ...

A vast and evolving anomaly in Earth’s magnetic field, situated above South America and the southern Atlantic Ocean, ...

Developed by engineers at the University of Leeds, the robot can generate high-resolution three-dimensional ultrasound images ...

As it turns out, the ability to nullify the powerful magnetic field from ... Perhaps even a 3D-printed version would be possible. This isn’t the first switchable magnet we’ve seen, of course ...

A flower-shaped structure only a few micrometers in size made of a nickel-iron alloy can concentrate and locally enhance ...

This means that their magnetism is there all the time and cannot be turned on or off as it can with an electromagnet. Converting a magnet to a non-magnet is called demagnetisation. Magnets are ...

A permanent magnet is always magnetic. It has an invisible magnetic field. Only certain materials, such as iron, feel a magnetic force. Permanent magnets can come in lots of different shapes and ...
