Question

If 140 N force is acting on a wire of length 70cm carrying 40A current is kept in a magnetic field with an angle of 30 degrees to the field calculate the magnetic field strength

Answer 1

Answer:

10 Tesla

Explanation:

As we know the , the magnetic force on a current carrying wire is given by

OR

If a straight wire of length (l) carrying a current (i) is placed in a uniform magnetic field B ,the force it is ..

✧ F=i L×B

= $ilb \sin \theta$.

so put the value of given condition.
