Question

An electron projected towards west, is deflected towards north by a magnetic field. What is the direction of the magnetic field?

Answer 1

Hii There!!

Direction of magnetic field is upward.
It can be determined by Fleming's Left hand rule.


Hope it helps

Answer 2

The direction of field will be upward.

Explanation:

Given that,

An electron projected towards west is deflected towards north by a magnetic field.

We know that,

Flaming left hand rule :

According to flaming left hand rule, the thumb, forefinger and middle finger are perpendicular to each other.

The thumb shows the direction of force.

The forefinger shows the direction of field.

The middle finger shows the direction of current.

If an electron projected towards west is deflected towards north by a magnetic field that means the direction of current in west and the direction of force in north.

So, the forefinger shows the direction of field is upward.

Hence, The direction of field will be upward.
