List of top Physics Questions on Magnetic Field asked in AIIMS

In toroid magnetic field on axis will be radius = 0.5 cm, current = 1.5A, turns = 250, permeability = 700.

The magnetic field at the centre O of the arc shown in the figure is

Magnetic field interacts with a moving charge and not with a stationary charge. A moving charge produces a magnetic field.

The magnetic field at $P$ on the axis of a solenoid having $100$ turn/ $m$ and carrying a current of $5\, A$ is

A bar of magnetic substance is placed in a magnetic field with its length making an angle of $30^{\circ}$ with the direction of the magnetic field. How will the bar behave?

The magnetic field produced by a current carrying solenoid is independent of its length and cross-sectional area. The magnetic field inside the solenoid is uniform.

The magnetic field due to a straight conductor of uniform cross-section of radius a and carrying a steady current is represented by

A proton and an $\alpha$ - particle, moving with the same velocity, enter into a uniform magnetic field, acting normal to the plane of their motion. The ratio of the radii of the circular paths described by the proton and $\alpha$ - particle is

The magnetic needle of a tangent galvanometer is deflected at an angle $30^{\circ}$ due to a magnet. The horizontal component of earth's magnetic field $0.34$ $\times 10^{-4} T$ is along the plane of the coil. The magnetic intensity is
