Science : Ch 13 – Magnetic Effects of Electric Current

A current-carrying conductor is clench in totally vertical direction. In order to produce a clockwise magnetic feld around the conductor, the current should passed in the conductor:

The magnetic feld inside a long straight solenoid carrying current is:

Relative strength of magnetic field at a point in the space adjoining the magnet is shown by the:

A soft iron bar is introduced inside the current carrying solenoid. The magnetic field inside the solenoid:

When current is parallel to magnetic field, then force experience by the current carrying conductor placed in uniform magnetic field is

Direction of rotation of a coil in electric motor is intent by:

The instrument that use to direct electric current in the circuit is known as:

Overloading is caused to:

The current which is created due to the relative motion of coil or magnet

The change in magnetic feld lines in a coil is the cause of induced electric current in it. Name the underlying phenomenon.

The magnetic feld inside a long straight solenoid carrying current is

The deflection of the galvanometer becomes zero the moment the motion of

A device that can convert electrical energy into mechanical energy is

Two magnetic feld lines never intersect because the resultant force on a north pole at any point can only be in

When a strong bar magnet is pushed into a coil of insulated copper wire connected to a galvanometer, we will observe a deflection in the galvanometer in
