Science : Ch 13 – Magnetic Effects of Electric Current

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

The nature of magnetic field line passing through the centre of current carrying circular loop is:

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

Which of the following component influence the strength of force experience by a current carrying conduct in a uniform magnetic field?

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

A magnet is moved towards a coil (i) quickly (ii) slowly. The induced potential difference:

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

To determine the direction of force experienced by a current carrying conductor placed in a uniform magnetic feld.

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 phenomenon discovered by Faraday.

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

A device that can convert electrical energy into mechanical energy is

You are holding the current-carrying wire in your right hand so that your thumb points in the direction of current, then the direction in which your fingers encircle the wire will give the direction of the magnetic feld lines around the wire.explain

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
