Answer to Question #3837 in Electric Circuits for mia
A wire 75 cm long carrying a current of 6.0 A is at right angles to a uniform magnetic field. The magnitude of the force acting on the wire is 0.60 N. What is the strength of the magnetic field ?
According to the Ampere's law:
F - the Ampere's force,
B - strength of the magnetic field,
I - amperage in a wire,
L - length of a wire,
A - angle between the amperage and the vector of magnetic field
As the wire is at the right angles, we will get that:
The strength of the magnetic field is 0.13 tesla.
