Question

1. State the effects of current.
2. Why does a compass needle placed near a current carrying wire show deflection?
3. How can the magnetic field produced around a current carrying conductor be
detected?
4. Give one example each of the following:- (a) magnetic effect of electric current (b)
electric effect of moving magnets
5. Define magnetic field.
6. Give the characteristics of magnetic field lines.
7. With the help of an activity show how magnetic field lines around a bar magnet can
be obtained. Also draw the pattern of magnetic field lines around a bar magnet.
8. How is the deflection in the compass needle affected as we move it along a field line
(a) towards the poles (b) away from poles.
9. State the factors on which strength of magnetic field due to a straight current carrying
conductor depends.
10 "The concentric circles representing the magnetic field around a current carrying
from it " What conclusion can be drawn from this statement​

Answer 1

Explanation:

1. when current is passed it produces three effecte

1 chemical

2 heat

3 magnetic

2 due to passing current wire produces magnetic field and compass shows deflection

3 using a magnetic needle it shows deflection

4 magnetic field is produced when current is passed

b) induced current is produces on moving magnet

6 they do not intersect each other

Answer 2

Answer:

• Brainlist Answer

2. because a current carrying wire has magnitude and a compass comes in the influence of the wire then the magnitude starts forcing on the compass so that's why it show deflection.
