List of top Physics Questions on Moving charges and magnetism asked in TS EAMCET

A straight wire carrying a current of \( 2\sqrt{2} \, \text{A} \) is making an angle of \( 45^\circ \) with the direction of a uniform magnetic field of \( 3 \, \text{T} \). The force per unit length on the wire due to the magnetic field is:
The most exotic diamagnetic materials are:
A current \( i \) flows through a circular loop of radius \( R \). The ratio of the magnetic field produced at its centre to the field produced at a point at a distance \( \frac{R}{\sqrt{3}} \) from its centre on its axis is:
If the amplitude of the magnetic field part of a harmonic electromagnetic wave in vacuum is \( 270 \) nT, the amplitude of the electric field part of the wave is:
The magnetizing field which produces a magnetic flux of \(22 \times 10^{-6} \, \text{Wb}\) in a metal bar of area of cross-section \(2 \times 10^{-5} \, m^2\) is (susceptibility of the metal = 699):
