Questions & answers

  1. In a non-uniform magnetic field, a metallic wire coil remains immobile. What is the coil’s induced emf?

Answer: Since the magnetic flux coupled to the secondary coil does not vary, no emf is induced in the coil.

  • Whenever a metallic object is encircled by a coil conveying high frequency (H.F) alternating current, how does it get extremely hot?

Answer: When a metallic component is encircled by a coil carrying a high frequency (H.F) alternating current, eddy currents are formed, resulting in the joule’s heating effect.

  • Maybe because a copper disc’s vibrations in a magnetic field minimally damped?

Answer: The creation of eddy currents opposes the oscillating motion of the copper disc, causing it to oscillate. As a result, the motion is dampened.

  • Inside a non-uniform magnetic field, a metallic wire coil remains immobile. What is the magnitude of the induced emf in the coil?

Answer: Because the magnetic flux coupled to the secondary coil does not vary, no emf is induced in the coil.

  • In the following cases, use Lenz’s law to identify the source of induced current:
    An irregularly shaped wire that transforms into a circle form.

Answer: The direction of the magnetic field emf, as per Lenz’s law, tends to create a current that opposes the change in magnetic flux that caused it. Since the wire is extending to create a circle, the magnetism is exerting force outwards on each section of the wire. Furthermore, the direction of the induced flow will be such that it produces an upward magnetic field. As a result, the stress on the wire would be inward, causing induced power to pass in an anticlockwise direction in the loop. Deforming a circular loop into a thin straight wire. The flux penetrating the surface diminishes as a circular loop is deformed into a narrow straight wire. As a result, the induced current follows Lenz’s law and flows along.

  • How can you tell the difference between resistance, reactance, as well as impedance in an a.c electrical circuit?

Answer: They can be classified as follows:
The resistor opposes the passage of electricity by providing resistance. It is unaffected by the source’s frequency.
Inductor and capacitor reactance is the resistance to current flow given by the inductance or capacitor. It is dependent on the outlet’s frequency.
Impedance: The opposition is provided by a resistance, inductance, or capacitance in combination. It is dependent on the source’s frequency.

  • A metal rod PQ is placed between both the poles of a permanent magnet and rests on smooth rails AB. The magnetic field, the rails, and the rod are all perpendicular to each other. Throughout a switch K, a galvanometer G links the rails. Rod length is 15cm, B is 0.50T, and the resistivity of the closed loop holding the rod is 9.0m. Suppose that the playing field is equal. When K is open, does an extra charge build up at the rod ends? What happens if K isn’t open? 

Answer: Indeed, while key K is closed, the continuous flow of current can keep the extra charge going. Excessive charge builds up at both rod ends when key K is open, however when key K is closed, excess charge is retained by the continual flow of current. Even if the electrons in the rod PQ feel magnetic force owing to the rod’s motion, there is no net force on them with K open as well as the rod moving evenly. The electric force created by the surplus charge of opposing nature at both rod ends cancels out the magnetic force. Whenever key K is open and the rod travels equally, there is no net force on the electrons in rod PQ. Due to the obvious excess charge of opposing nature at it from both extremities of the rods, the magnetic force is neutralised by the electric force setup.

Now, can you solve this question:

A Sinusoidal voltage V = 200 sin 314 t r is applied to a resistor of 10 ohm. Calculate :

  • rms value of voltage
  • rms current
  • power dissipated as heat.
