Answer :
Final answer:
In a uniform magnetic field the current from the given values is 0.67A. Therefore, the correct answer is a) 0.67 A.
Explanation:
To find the current, we use the formula for the magnetic force on a current-carrying conductor: F = BIL where F is the magnetic force, B is the magnetic field strength, I is the current, and L is the length of the wire. The formula to calculate the magnetic force on a current-carrying wire in a magnetic field is:
F = BIL sin(theta)
Given that the wire length is 1.5m, force is 2.0N, and magnetic field is 1.8T, we can rearrange the formula to solve for current:
- I = F / (B x L)
Plugging in the values, we get:
- I = 2.0N / (1.8T x 1.5m) = 0.67A
Therefore, the correct answer is a) 0.67 A.
