- Does AC current create magnetic effect?
- if south pole attract north and north pole attract south. so, when we use magnetic compass, north pole of magnetic needle tell the direction by arrow which is of north pole. so, what is this explain me Please
- explain an activaty to plot the magnetic field lines produced around a straight current carrying conductor
- Which among iron and mercury is a better conductor?
-
please solve ques e (i) part
- what is meant by polarity
- Two circular loop of radii 10cm and 40cm carries current of 1A and 2A respectively. Find the ratio of magnitude of magnetic field at their centres
