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.
2. Technical data
Dimensions:
Operating voltage:
175 x 65 x 70 mm³
6 V max.
3. Additionally required equipment
1 DC Power Supply 0 - 20 V, 0 - 5 A (230 V, 50/60 Hz)
or
1 DC Power Supply 0 - 20 V, 0 - 5 A (115 V, 50/60 Hz)
•
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.
