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:

Inside the magnet, the field lines move from :

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:

Which of the following declaration is not correct about the magnetic field?

By which instrument, the presence of magnetic field be resolved?

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

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

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
