Question

A wire carrying a 25 A current passes between the poles of a strong magnet so that it is perpendieular to the field and experiences in 2.14 N force on the 4.75 cm of wire in the field.

A What is the average field strength (T) ? B=

Answer 1

To find the average field strength, use the formula: Force = Current × Length × Magnetic Field Strength. Substituting the given values, the average field strength is 1.02 T.

Step-by-step explanation:

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

Force = Current × Length × Magnetic Field Strength

In this case, the force is given as 2.14 N, the current is 25 A, and the length is 4.75 cm (or 0.0475 m).

By rearranging the formula, we can solve for the average field strength:

Field Strength = Force / (Current × Length)

Substituting the given values, we get:

Field Strength = 2.14 N / (25 A × 0.0475 m) = 1.02 T

Therefore, the average field strength is 1.02 T.
