Describe an experiment with a diagram to show that force is exerted on a current carrying conductor
when placed perpendicular in a magnetic field.
(b) How will this force change if current in the conductor is increased?
(c) Name a device that uses the above principle.
Answers
Answer:
To show that force is exerted on a current carrying conductor.
1. Take a aluminium rod and hand it on a handle with the help of a thread.
2. Take a horse shoe magnet such that the aluminium rod lies between the poles of the magnet .
3. Connect the rod to battery and key and complete the circuit.
Observation : The rod will either be repelled or attracted by magnet .
Result : Force acts on a current carrying conductor when placed inside a magnetic field.
b) If current will increase force will also increase.
c) Electric motor uses this principle . The motor rotates because of the force exerted by magnetic field on the coil.
Hope it helps you!!!!
Answer:
Explanation:
A small aluminium rod suspended horizontally from a stand using two connecting wires. Place a strong horseshoe magnet in such a way that the rod lies between the two poles with the magnetic field directed upwards. For this, put the north pole of the magnet vertically below and south pole vertically above the aluminium rod. Connect the aluminium rod in series with a battery, a key and a rheostat. Pass a current through the aluminium rod from one end to other (B to A). The rod is displaced towards left. When the direction of current flowing through the rod is reversed, the displacement of rod across towards right.
