Q1Magnetism Core Principles

Expected: 60sEasy

Current sensitivity of a moving coil galvanometer is 5 div/mA and its voltage sensitivity (angular deflection per unit voltage applied) is 20 div/V. The resistance of the galvanometer is

Q2Magnetism Advanced Applications

Expected: 60sEasy

A metallic rod of mass per unit length 0.5 kg m–1 is lying horizontally on a smooth inclined plane which makes an angle of 30° with the horizontal. The rod is not allowed to slide down by flowing a current through it when a magnetic field of induction 0.25 T is acting on it in the vertical direction. The current flowing in the rod to keep it stationary is

Q3Magnetism Problem Solving Techniques

Expected: 60sEasy

A thin diamagnetic rod is placed vertically between the poles of an electromagnet. When the current in the electromagnet is switched on, then the diamagnetic rod is pushed up, out of the horizontal magnetic field. Hence the rod gains gravitational potential energy. The work required to do this comes from

Q4Magnetism Core Principles

Expected: 60sEasy

A 2 amp current is flowing through two different small circular copper coils having radii ratio $1: 2$ . The ratio of their respective magnetic moments will be

Q5Magnetism Advanced Applications

Expected: 90sMedium

An electron (mass $9 \times 10^{-31} \mathrm{~kg}$ and charge $1.6 \times 10^{-19} \mathrm{C}$ ) moving with speed $c / 100(c=$ speed of light) is injected into a magnetic field $\vec{B}$ of magnitude $9 \times 10^{-4} \mathrm{~T}$ perpendicular to its direction of motion. We wish to apply an uniform electric field $\vec{E}$ together with the magnetic field so that the electron does not deflect from its path. Then (speed of light $c=3$ $\times 10^3 \mathrm{~ms}^{-1}$ )

Q6Magnetism Problem Solving Techniques

Expected: 120sHard

A model for quantized motion of an electron in a uniform magnetic field $B$ states that the flux passing through the orbit of the electron in $n(h l e)$ where $n$ is an integer, $h$ is Planck's constant and $e$ is the magnitude of electron's charge. According to the model, the magnetic moment of an electron in its lowest energy state will be ( $m$ is the mass of the electron)

Q7Magnetism Core Principles

Expected: 120sHard

A parallel plate capacitor made of circular plates is being charged such that the surface charge density on its plates is increasing at a constant rate with time. The magnetic field arising due to displacement current is:

Q8Magnetism Advanced Applications

Expected: 90sMedium

Nickel shows ferromagnetic property at room temperature. If the temperature is increased beyond Curie temperature, then it will show

Q9Magnetism Problem Solving Techniques

Expected: 90sMedium

A magnetic needle suspended parallel to a magnetic field requires $\sqrt 3 J$ of work to turn it through 60o. The torque needed to maintain the needle in this position will be

Q10Magnetism Core Principles

Expected: 90sMedium

If $\theta$ 1 and $\theta$ 2 be the apparent angles of dip observed in two vertical planes at right angles to each other, then the true angle of dip $\theta$ is given by
