Science : Ch 13 – Magnetic Effects of Electric Current

Fleming’s Right-hand rule gives:

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:

Which of the following declaration is not correct about the 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:

Overloading is caused to:

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

Example of permanent magnet is

A coil of many circular turns of wire wrapped in the shape of a cylinder

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

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

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
