Little Big Coil: the record-breaking magnet is the size of a toilet roll core. (Courtesy: Stephen Bilenky/National MagLab) The highest continuous magnetic field ever created in the lab has been ...

Place wire and compasses, if desired, under document camera or on projector. If using document camera, place sheet of paper underneath for visibility. If using an overhead projector, focus it on the ...

Equipment: A compass, iron filings, a current carrying solenoid and a 40 Amp power supply. What it does: The compass shows the direction of the field lines in and around the solenoid. The iron filings ...

Resistive magnets are built in-house at the magnet lab using so-called Florida Bitter technology pioneered by researchers there. Circular plates of copper sheet metal are stamped with cooling holes; ...

(Nanowerk News) In the drive to miniaturize electronics, solenoids have become way too big, say Rice University scientists who discovered the essential component can be scaled down to nano-size with ...

Key learning points Properties of magnets What are magnetic fields? Magnetic fields lines are invisible but they fill the space around a magnet where the magnetic forces work on magnetic materials, ...

The film demonstrates an experiment using an apparatus to observe the behavior of electrons in a uniform magnetic field. It explains how electrons are accelerated by an electron gun and then deflected ...
