Question

A wire carrying a 42.5 a current passes between the poles of a strong magnet so that it is perpendicular to the field and experiences a 2.15 N force on the 4.75 cm of wire in the field. What is the average field strength?

Answer 1

To find the average field strength, use the formula B = F / (I * L), where B is the magnetic field strength, F is the force on the wire, I is the current through the wire, and L is the length of the wire in the magnetic field. In this case, the average field strength is approximately 0.0101 T.

Step-by-step explanation:

To find the average field strength, we can use the formula:

B = F / (I * L)

Where B is the magnetic field strength, F is the force on the wire, I is the current through the wire, and L is the length of the wire in the magnetic field. In this case, the force is given as 2.15 N, the current is 42.5 A, and the length of the wire is 4.75 cm (converted to meters by dividing by 100). Plugging in these values, we get:

B = 2.15 / (42.5 * 0.0475)

Simplifying the equation, we find that the average field strength is approximately 0.0101 T.
