  • The wire gets hot when an electric current passes through it. This is the heating effect of the electric current. Oersted observed the deflection of the compass needle every time the current was passed through the wire.
  • So, when electric current passes through a wire, it behaves like a magnet. This is the magnetic effect of the electric current.

Wire Heating and Magnetic Effects of Electric Current

Wire Heating
- Assertion 1 is correct as the wire does indeed get hot when an electric current passes through it.
- This is due to the resistance of the wire to the flow of electrons, which generates heat as a byproduct.
- The amount of heat produced is directly proportional to the square of the current passing through the wire and the resistance of the wire.

Magnetic Effects
- Assertion 2 is also correct as when an electric current passes through a wire, it produces a magnetic field around it.
- This phenomenon is known as electromagnetism and is the basis for the operation of electromagnets in various devices.
- The strength of the magnetic field produced is directly proportional to the current passing through the wire.

Conclusion
- Both assertions are valid as they describe fundamental principles of the behavior of electric current in a wire.
- The wire heats up due to resistance, while it exhibits magnetic properties when current flows through it.
