Force on a Conductor in a Magnetic Field U30065

Instruction Sheet

11/08 ALF

1. Description

The apparatus is used to demonstrate the rolling motion of a current carrying conductor in the magnetic field of a magnet.

It consists of a powerful U shaped magnet mounted on a base plate, a pair of brass rails complete with 4 mm sockets and a brass axle.

A power supply unit is connected to the rails. When the axle is placed on the rails the electric circuit is completed and the axle is repelled along the rails in a direction either towards or away from the magnetic field. Reversing the current will have the opposite effect.

1 DC Power Supply 0 - 20 V, 0 - 5 A (230 V, 50/60 Hz) U33020-230

or

1 DC Power Supply 0 - 20 V, 0 - 5 A (115 V, 50/60 Hz) U33020-115

4.Operation

Connect the power supply to the sockets of the rails.

Place the axle onto the rails.

Switch on the power supply, apply a voltage of max. 6 V and observe the movement of the axle.

Fig. 1 shows the basic set-up of the apparatus. The magnetic field is vertical, while the current is flowing horizontally. This will move the axle at right angles to both the current and the magnetic field, as shown in fig. 1. If either the current or the magnetic field are reversed, then the axle should move in the opposite direction.
