C is the right choice.

When particles are neutral, no magnetic fields will be created.

The magnetic field deflects charged particles such as protons, cathode rays, and alpha particles. However, the neutrons are not deflected by the magnetic field because they are charge-free.

Heavy currents cannot be measured by a galvanometer because it is an extremely sensitive device. A very low resistance called “shunt” resistance is connected in parallel to a galvanometer in order to transform it into an ammeter.

The torque will cause the rod PQ to rotate clockwise if the specified arrangement is in a horizontal plane.

The screen displays the direction of the magnetic field caused by current i0 at point P according to the right-hand grip rule. The current flowing through rod PQ is directed from P to Q. According to Fleming’s left-hand rule, the force at point P is therefore closer to the top of the screen. The rod rotates in a clockwise direction because it is pivoting.

Option A is accurate because magnetic flux surrounds the conductor in proportion to the amount of current flowing through the primary coil of a transformer. The secondary coil is cut and a voltage is induced in it by the expanding and contracting flux. “Mutual induction” is this.

The equation F = qVBsinθ, where q is the charge, B is the magnetic field, V is the charge’s velocity, and θ is the angle between the velocity vector and the magnetic field vector, provides the force acting on a charge traveling through a magnetic field.

The angle between the velocity vector and the magnetic field vector in this instance is 0° since the electron is traveling along the line of force in magnetic field B. Sinθ = sin(0°) = 0 implies this.

When we enter sinθ = 0 into the formula F = qVBsinθ, we obtain:

F = qVB(0) = 0.

This indicates that there is no force acting on the electron, so choice D is the right one.

The representation of Eddy Current Loss is

(Ie)2 x Rcore = We

Where,

Eddy Current Loss = We

Eddy Current = Ie

Re = Core Resistance

According to the equation, it will not change based on the frequency or applied voltage.

Since the magnetic force is not doing any work, a charged particle projected perpendicular to a uniform magnetic field will revolve in a circle with a constant kinetic energy. Momentum changes when a particle’s circular path changes direction.
