Science : Ch 13 – Magnetic Effects of Electric Current

This test is designed based on NCERT Syllabus for Class 10 Topics : Magnetic Effects of Electric Current

Each time random 15 questions will be displaced
So retake the quiz till you have mastered all the questions

1 / 15

Fleming’s Right-hand rule gives:

magnitude of the induced current.

magnitude of the magnetic field

direction of the induced current

both, direction and magnitude of the induced current

2 / 15

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:

from top towards bottom

from left towards right

from bottom towards top

from right towards left

3 / 15

For a current in a long straight solenoid N and S-poles are created at the two ends. Among the subsequent declaration , the incorrect declaration is:

The feld lines inside the solenoid are in the form of straight lines, which indicates that the magnetic field is the same at all points inside the solenoid

The strong magnetic feld produced inside the solenoid can be used to magnetise a piece of magnetic material like soft iron, when placed inside the coil

The pattern of the magnetic feld associated with the solenoid is diferent from the pattern of the magnetic field around a bar magnet

The N and S-poles exchange position when the direction of current through the solenoid is reversed

4 / 15

Which of the subsequent is not attracted by a magnet:

Steel

Cobalt

Brass

Nickel

5 / 15

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

Magnetic field lines form a continuous closed curve

Magnetic field line do not interest each other

Direction of tangent at any point on the magnetic field line curve gives the direction of magnetic field at that point.

Outside the magnet, magnetic field lines go from South to North pole of the magnet.

6 / 15

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

Magnetic Needle

Ammeter

Galvanometer

Voltmeter

7 / 15

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