The magnetic feld inside a long straight solenoid carrying current is:

A soft iron bar is introduced inside the current carrying solenoid. The magnetic field inside the solenoid:

When current is parallel to magnetic field, then force experience by the current carrying conductor placed in uniform magnetic field is

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

The name of the effect being produced by the moving magnet

Which of the following is not attracted by a magnet:

The phenomenon discovered by Faraday.

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

At the time of short circuit, the electric current in the circuit:

The instrument used for measuring electric current is:

Insulators consists of:

The property of a conductor to oppose the flow of charges through it.

S.I unit of resistance

Joule’s law of heating implies that heat produced in a resistor is directly proportional to the square of

At the time of short circuit, the electric current in the circuit

An ideal ammeter is one which has

The device used to measure the internal resistance of a cell, to compare the e.m.f. of two cells and potential diference across a resistor

Why don’t planets twinkle?

When a fine beam of sunlight enters a smoke filled room, smoke particles become visible due to scattering of light by these particles

Light which consists of only one colour or single wavelength is called Monochromatic

Lenses which have both concave and convex structure.

Astigmatism can be corrected

Visible spectrum is the band of coloured components of a
