Science : Ch 13 – Magnetic Effects of Electric Current

Fleming’s Right-hand rule gives:

An electron moves with a speed v along positive direction of the x-axis. If a magnetic feld B acts along the positive y-direction, then the force on the electron will act along:

Which of the subsequent is not attracted by a magnet:

The magnetic field lines:

Magnetic effect of current was identified by:

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

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?

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

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

An electron moves with a speed v along positive direction of the x-axis. If a magnetic feld B acts along the positive y-direction, then the force on the electron will act along

The magnetic feld inside a long straight solenoid carrying current is

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

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
