Worksheet 2. Ampere force.

Worksheet 2. A current –carrying conductor in magnetic field.

Ampere’s force. Fleming left hand rule

1.      Fill the blanks

When a _____________ carrying conductor is placed in a ___________ __________ the magnet and the conductor exert a _________ on each other.

2.      4. Fleming’s left hand rule can be used to determine the direction of the force on the wire

3.      Describe 3 ways in which the force on the wire can be increased.

4.      A current carrying wire of length 0.03m is placed at right angles to the field from a magnet. The magnetic flux density, B produced by the magnet is 0.05T. A current of 3.0A flows through the wire. Use the equation 𝐹 = 𝐵𝐼𝑙 to calculate the force on the wire.
