Question

(a) Consider a circular loop of wire lying in the plane of the paper. Let the current pass through the loop clockwise. With the help of a diagram explain how the direction of the magnetic field can be determined inside and outside the loop. Name the law used to find the direction of magnetic field. (b) Draw a diagram to represent a uniform magnetic field in a given region. (c) List two properties of magnetic field lines.

plz answer it fast...

Answer 1

Law used to find direction of magnetic lines of force is right hand thumb rule imagine first current is flowing from down to up so your thumb will be upward direction and after that current will flow from up to down now your thumb will be in downward direction curling of your finger will show direction of magnetic field.

Two properties are

Magnetic field line are straight and parallel in centre of loop

Magnetic field lines are in same direction.

Hope it helps.

Answer 2

Right Hand Thumb rule

Imagine first current is flowing from down to up so your thumb will be upward direction and after that current will flow from up to down now your thumb will be in downward direction curling of your finger will show direction of magnetic field.

THIS WILL GIVE THE DIRECTION OF MAGBNETIC FEILD LINES INSIDE AND OUTSIDE THE LOOP
