A magnet falling down a copper tube is slowed by magnetic fields from eddy currents induced in the tube. A magnet falling down a glass tube is unaffected. Set up lab stands, each with a 3-finger clamp ...

To start things off, what even is a permanent magnet? Like many simple questions about nature, there’s no easy answer that ... material were developed. These experiments showed that these ...

It solves a long-running problem for [mulcmu], after their experiments with techniques inspired ... which allows the user to feed solder through using an easy motion of the thumb.

The motion of a solid metal plate moving in and out between the poles of a strong magnet is damped out by eddy currents. When the slotted edge of the plate is used, the braking effect of induced eddy ...
