Question

In a 10 cm long horizontal wire, 5 Amp current is flowing. The mass of the wire is \(3 \times 10^{-3}\) kg/m. What will be the field to keep wire stable?

• A. \(5.88 \times 10^{-6}\) Tesla downward
• B. 0.6 \(\times 10^{-3}\) Tesla upward
• C. \(5.88 \times 10^{-3}\) Tesla upward
• D. \(5.88 \times 10^{-3}\) Tesla downward

Hint:

To find the magnetic field, use the relation between current, magnetic force, and length of wire.

Answer 1

The Correct Option is C

We can use the formula \(B = \frac{F}{IL}\), where \(F = 5 \, \text{A} \times L\), and the given values.
