Question

describe the activity that shows the pattern of magnetic field lines produced due to :
1. a current through a circular loop
2. a current carrying straight conductor
3. a current carrying solenoid
Give the direction of current & magnetic field in each case.


Answers quickly & completely plzzzzz

Answer 1

1. current through circular loop is called ohm's law... is equal to v\R
2. current carrying straight conductor following flemming right hand rule
3. Magnetic Field of a Solenoid Carrying Current A solenoid is a long cylindrical coil. It is made by winding many turns of wire on a cylinder.

Answer 2

Answer:

Explanation:

Activity

Take a battery (12 V), a variable resistance (or a

rheostat), an ammeter (0-5 A), a plug key, and

a copper wire that is long, straight and thick.

Insert the thick wire through the centre, normal

to the plane of a rectangular cardboard. Take care

that the cardboard is fixed and does not slide.

Connect the copper wire vertically between the

points X and Y, as shown in diagram in series

with the battery, a plug and a key. Sprinkle some

iron filings uniformly on the cardboard. Keep the

variable of the rheostat at a fixed position and note

the current through the ammeter.
