Answer :
The current in the wire is 0.00975 A.
What is electric current?
Elecric current is the rate of flow of charge in a circuit.
To calculate the current in the wire, we use the formula below.
Formula:
- F = BILsin∅............... Equation 1
Where:
- F = Force
- B = Magnetic field
- I = Current in the wire
- L = Length of the wire
- ∅ = Angle between the wire and the field
make I the subject of the equation
- I = F/BLsin∅........... Equation 2
Given:
- F = 7.6 mN = 0.0076 N
- B = 4.1 T
- L = 19 cm = 0.19 m
- ∅ = 90° (perpendicular)
Substitute the given values into equation 2
- I = (0.0076)/(4.1×0.19×sin90°)
- I = 0.0076/0.779
- I = 0.00975 A
Hence, The current in the wire is 0.00975 A.
