Answer:
Magnetic force, F = 0.6 N
Explanation:
It is given that,
Length of the wire, L = 30 cm = 0.3 m
Current carrying in the wire, I = 0.5 A
Uniform magnetic field, B = 4 T
To find,
The magnetic force
Solve,
A force is exerted by the wire in the magnetic field that is given by :
[tex]F=ILB\ sin\theta[/tex]
Here, [tex]\theta=90[/tex]
[tex]F=ILB[/tex]
[tex]F=0.5\ A\times 0.3\ m\times 4\ T[/tex]
F = 0.6 N
Therefore, the magnetic force exerted by the wire in the magnetic field is 0.6 N
