Answer:
The magnetic field is 1.23 T in upward.
Explanation:
Given that,
Mass = 0.2
Length = 0.8 m
Current = 2 A
We need to calculate the magnetic field
If the net force on the rod is zero so the magnetic field is equal to the weight.
Using formula of magnetic force
Put the value into the formula
For direction, using right hand rule
In right hand rule, Thumb represents the force, forefinger represents the magnetic field and the middle finger represents the current.
So,
The direction of the magnetic field is upward.
Hence, The magnetic field is 1.23 T in upward.
