A Current carrying wire is placed in a magnetic field where magnetic field is perpendicular to the plane of the conductor. What will happen to the force applied on the conductor if the current in wire is doubled? Correct Answer Doubled

CONCEPT:

  • Magnetic field: The space or region around the current carrying wire/moving electric charge or around the magnetic material in which force of magnetism can be experienced by other magnetic material is called as magnetic field/magnetic induction by that material/current. It is denoted by B.
  • When a current carrying wire is placed in a magnetic field then it experiences a magnetic force on it.

The magnetic force on a current carrying wire is given by:

F = I L B Sin θ

Where I is current in wire, L is length of the wire, B is magnetic field and θ is angle between current and magnetic field.

EXPLANATION:

  • Since magnetic force F = I L B Sin θ is force on the current wire in magnetic field. Here the force is directly proportional to the current flowing in the circuit.
  • If the current flowing in the circuit is doubled then the force on the wire will also double. So option 1 is correct.
