Dip Needle

Description

For investigating magnetic field around a wire. Maximum current is approx. 8A. diameter of wire is 1.5 mm.

Description

A wooden table supports a plastic ring wound with three coils of 5, 10 and 20 turns of insulated copper wire, connected to terminals on the base.

Description

For investigating the magnetic field associated with a solenoid coil. Coil size 51 x 92 mm.(diameter x length) approx.,diameter of wire 1.5 mm. Magnetic field Demo, long solenoid

Description

To demonstrate that when a current is passed through a conductor in a magnetic field, it is subjected to attraction or repulsion depending upon the direction of current in it. The apparatus consists of a plastic base 160 x 140 mm on which two contact pillars are mounted. Each pillar is provided with an external circuit. A balanced beam is supported by the pillars on two bearings which form the fulcrum. Two screwed masses are provided in the beam system, one moving vertically for the adjustment of sensitivity and the other moving horizontally for the adjustment of the equilibrium position, when no current is flowing. Scale marked 0 to 75 x 1 mm, rider of 1 gm. weight with instruction manual.
