In a magnetic field, if a current of 0.3 A flows for 0.75 seconds, and the magnetic field strength is 0.2 T, what will be the force experienced by the current-carrying conductor?
Show Hint
The force on a current-carrying conductor in a magnetic field depends on the magnetic field strength, the current, and the length of the conductor within the field.
Step 1: Force formula in a magnetic field.
The force \( F \) experienced by a current-carrying conductor in a magnetic field is given by the equation:
\[
F = BIL
\]
where:
- \( B = 0.2 \, \text{T} \) (magnetic field strength),
- \( I = 0.3 \, \text{A} \) (current),
- \( L = 1 \, \text{m} \) (length of the conductor in the field).
Step 2: Calculating the force.
Substituting the values into the equation:
\[
F = 0.2 \times 0.3 \times 1 = 0.06 \, \text{N}
\]
Step 3: Conclusion.
The correct answer is \( 0.06 \, \text{N} \), so the correct answer is (A).
