J6 Electromagnets

This section contains demonstrations of electromagnets and their applications.

J6-01: ELECTROMAGNET WITH BANG
Illustrate the force which can be exerted by a small electromagnet.
J6-02: ELECTROMAGNET WITH JUNK
Demonstrate an electromagnet.
J6-03: ELECTROMAGNET WITH JUNK - WITHOUT CORE
Demonstrate electromagnetism.
J6-04: LOW-POWER HIGH-FORCE ELECTROMAGNET
Show that a small amount of energy can produce large magnetic forces
J6-21: MAGNETIC FIELD IN GAP OF ELECTROMAGNET
Semi-quantitatively measure the magnetic field in the air gap of a magnet.
J6-31: FORCE ON SOLENOID CORE
Demonstrate the force exerted on the core of an electromagnet.
J6-32: FORCE ON SOLENOID CORE - SMALL
Demonstrate the force exerted on the core of an electromagnet.
J6-33: ELECTROMAGNETIC GUN
Demonstrate the force on a solenoid core, and to contrast forces on magnetic and non-magnetic cores.
