If a wire carries a current of 5 A and is placed in a magnetic field of 0.1 T, what is the force per unit length on the wire?
0.5 N/m
1 N/m
0.2 N/m
0.1 N/m
Using the formula F = BIL, where B is the magnetic field, I is the current, and L is the length of the wire (1 m), F = 0.1 T * 5 A * 1 m = 0.5 N.

Q
Q: If a wire carries a current of 5 A and is placed in a magnetic field of 0.1 T, what is the force per unit length on the wire?
Solution: Using the formula F = BIL, where B is the magnetic field, I is the current, and L is the length of the wire (1 m), F = 0.1 T * 5 A * 1 m = 0.5 N.
Steps: 6
Step 1: Identify the values given in the problem. The current (I) is 5 A and the magnetic field (B) is 0.1 T.
Step 2: Understand the formula to calculate the force (F) on the wire. The formula is F = BIL, where L is the length of the wire.
Step 3: Assume the length of the wire (L) is 1 meter for this calculation.
Step 4: Substitute the values into the formula: F = 0.1 T * 5 A * 1 m.
Step 5: Calculate the force: F = 0.1 * 5 * 1 = 0.5 N.
Step 6: The force per unit length on the wire is 0.5 N.
