Q1PhysicsUnit 13: Magnetic Effects of Current and Magnetism

The direction of magnetic lines of forces close to a straight conductor carrying current will be -

Q2PhysicsUnit 13: Magnetic Effects of Current and Magnetism

A long coil containing a large number of close turns of insulated copper wire.

Q3PhysicsUnit 13: Magnetic Effects of Current and Magnetism

A long solenoid has magnetic field strength of

3.14 \times 10^{-2} \mathrm{T}

inside it when a current of

5 A

passes through it The number of turns in 1 m of the solenoid is

Q4PhysicsUnit 13: Magnetic Effects of Current and Magnetism

A straight wire lying in a horizontal plane carries a current from north to south. What will be the direction of magnetic field at a point just underneath it?

Q5PhysicsUnit 13: Magnetic Effects of Current and Magnetism

Assertion If the current in a solenoid is reversed in direction while keeping the same magnitude, the magnetic field energy stored in the solenoid decreases. Reason Magnetic field energy density is proportional to square of current
