Science : Ch 13 – Magnetic Effects of Electric Current

Fleming’s Right-hand rule gives:

Which of the subsequent is not attracted by a magnet:

The magnetic field lines:

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:

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

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

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

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.

Which of the following is not attracted by a 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 law states that if the forefinger indicates the direction of the magnetic field and thumb shows the direction of motion of conductor, then the middle finger will show the direction of induced current

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
