Current in the circuit in Electromagnetism- Class 10 Science Experiment

In this experiment, we will investigate the effect of a current-carrying wire on a wooden plank when exposed to a magnetic field. The wooden plank has two long wooden sticks fixed on it, with a copper wire passing through the splits of these sticks.

The ends of the copper wire are connected to a 3-volt battery through a switch, creating a closed circuit. When the circuit is closed, a current passes through the wire. We will then bring a horseshoe magnet near the copper wire to observe its deflection.

Required Items:

  1. Wooden plank
  2. Two long wooden sticks
  3. Copper wire
  4. Horseshoe magnet
  5. 3-volt battery
  6. Switch

Step by Step Procedure:

  1. Fix the two long wooden sticks on the wooden plank, ensuring they are split at their top ends.
  2. Pass a copper wire through the splits in the wooden sticks.
  3. Connect the ends of the copper wire to the 3-volt battery using a switch to create a closed circuit.
  4. Close the switch to allow current to pass through the wire.
  5. Bring the horseshoe magnet near the copper wire and observe its deflection.

Experiment Observations:

  • The copper wire deflects when the current passes through it and the horseshoe magnet is brought near it.
  • The direction of deflection is observed by applying the right-hand thumb rule, which helps determine the direction of the force acting on the wire.


  1. Handle the electrical components (battery, wire, and switch) with care to avoid accidents.
  2. Do not touch the wire or any part of the circuit when it is connected to the battery and the switch is closed.
  3. Ensure the wooden plank and sticks are firmly fixed to provide a stable setup.
  4. Keep the magnetic field away from electronic devices, as it may cause interference.

Lesson Learnt from Experiment:

This experiment demonstrates the relationship between electric currents and magnetic fields. When a current flows through a wire, it generates a magnetic field around it.

The interaction between the magnetic field produced by the current-carrying wire and the external magnetic field of the horseshoe magnet results in the deflection of the wire. The direction of deflection can be determined using the right-hand thumb rule, which aligns with the theoretical expectations.
