Question

Magnetic field due to a current through a circular loop and magnetic field due to a current in a solenoid

Answer 1

Hey Friend,

Ф Magnetic filed due to current through a circular loop - 

1. The magnetic lines of force are concentrated near the coil where the current enters or leaves the coil.

2. Within the space enclosed by the coil, the lines of force are in same direction.

3. The magnetic field lines are parallel near center.

4. At the center of the coil, the plane of magnetic lines of force is at right angle to the plane of circular coil.

5. The intensity of magnetic field increases with the strength of current.

Ф Magnetic field due to a current in a solenoid - 

1. A solenoid carrying current behaves like a magnet.

2. The magnetic field lines are parallel to each other within the solenoid and parallel to the axis of solenoid.

3. Intensity of magnetic field can be increased.

Hope it helps!

Answer 2

hey friend !!

Here is ur answer .

short but content quality .
××××××××××××××××××××××××

➡ Magnetic field lines due to a current carrying conductor .

Magnetic field lines dur to circular current carrying conductor are in the form of concentric circles on both the sides.

▶As we know that towards the centre of loop the field lime become straight .

➡ Magnetic field lines due to current carrying solenoid .

❇Selenoid - A solenoid is formed by winding a number of turns of insulator wire over a non conducting material .

✴The magnetic fields produce due to a current carrying solenoid almost same like due to a bar magnet .

✴The magnetic field lines near the piles of the solenoid are more seperated .

Hope it helps you !!
