Question

a positively charged particle projected towards West deflected by a magnetic field towards north .find the direction of magnetic field

Answer 1

A positively charged Alpha particle projected towards west is deflected towards north by magnetic field then the direction of the magnetic field will? Using Fleming's left hand rule: pointyour centre finger towards west and thumb towards north.

Answer 2

Answer:

The direction of magnetic field will be upward.

Explanation:

According to flaming's left hand rule,

The thumb represent the direction of motion , index finger represents the magnetic field an the middle finger represents the direction of current. The middle finger mutually perpendicular to each other.

So,

A positively charged particle towards west that means the direction of current is towards west and the direction of magnetic force towards north.

Hence, The direction of magnetic field will be upward.
