Current through coil in Electromagnetism- Class 10 Science Experiment

Activity Name: Current through coil in Electromagnetism

Activity Description:

The experiment aims to demonstrate the concept of current flow through a coil and its magnetic effects on iron filings. A wooden plank covered with white paper is used as the base. Equidistant holes are made on the surface, and a copper wire is passed through these holes to create a coil.

The ends of the coil are connected to a battery through a switch to allow current flow. When the circuit is switched on, a magnetic field is generated around the coil.

Iron filings are then sprinkled on the paper surface around the coil. By giving a small jerk to the plank, the students can observe an orderly pattern of iron filings forming due to the magnetic field.

Required Items:

1. Wooden plank covered with white paper
2. Copper wire
3. Battery
4. Switch
5. Iron filings

Step by Step Procedure:

1. Take a wooden plank covered with white paper.
2. Make equidistant holes on the plank’s surface.
3. Pass a copper wire through the holes to create a coil.
4. Join the ends of the coil to a battery through a switch.
5. Switch on the circuit to allow current to pass through the coil.
6. Sprinkle iron filings on the surface of the plank around the coil.
7. Give a small jerk to the plank to observe the formation of an orderly pattern of iron filings due to the magnetic field.

Experiment Observations:

• Iron filings arrange themselves in an orderly pattern around the coil when current passes through it.
• The pattern of iron filings aligns with the magnetic field lines generated by the coil.

Precautions:

1. Use insulated copper wire to avoid short circuits.
2. Handle the battery and switch with care to prevent any accidents.
3. Avoid touching the coil or the circuit while it is powered to prevent electric shocks.

Lesson Learnt from Experiment:

Through this experiment, students learn that when current passes through a coil, it creates a magnetic field around it. The arrangement of iron filings indicates the direction of the magnetic field lines. This experiment helps to understand the fundamental principles of electromagnetism and the relationship between electric current and magnetic fields.
