The back face of a circular loop of wire is found to be south magnetic pole. The direction of current in this face of the circular loop of wire will be:
(a) towards south
(b) clockwise
(c) anticlockwise
(d) towards north
Draw a labelled diagram showing the three magnetic field lines of a loop carrying current. Mark the direction of current and the direction of magnetic field by arrows in your diagram.
A wire, bent into a circle, carries current in an anticlockwise direction. What polarity does this face of the coil exhibit?
A magnet kept at the centre of two coils A and B is moved to and fro as shown in the diagram. The two galvanometers show deflection. State with a reason whether : x > y or x< y [x and y are magnitudes of deflection.]
Answer the following question.
Explain with the help of the pattern of magnetic field lines the distribution of the magnetic field due to a current-carrying a circular loop.
Answer the following question:
Why is it that the magnetic field of a current-carrying coil having n turns, is 'n' times as large as that produced by a single turn (loop)?
State and illustrate the rule used for finding the polarity of the faces of a circular coil.
Meena draws magnetic field lines of field close to the axis of a current carrying circular loop. As she moves away from the centre of the circular loop she observes that the lines keep on diverging.
How will you explain her observation.
Why does a magnetic compass needle pointing North and South in the absence of a nearby magnet get deflected when a bar magnet or a current carrying loop is brought near it. Describe some salient features of magnetic lines of field concept.
