What is the strength of the magnetic field at the center of the loop in the figure?
Assume I = 6.0 A and d = 2.0cm
Concepts and reason
The concept used to solve this problem is magnetic field at the center of loop.
First, calculate the expression of magnetic field at the center of given loop. Finally, substitute the known values in the expression and calculate the magnetic field at center of the given loop.
Fundamentals
The expression of magnetic field due to a wire at distance R is given by,
The expression of magnetic field at the center of loop of radius R is given by,
Answer:
Explanation:
The magnetic field at the center of the loop is equal to the sum of magnetic field due to the circular loop and wire.
Calculate the magnetic field at the center of loop.
The radius of wire is equal to half of the diameter. The diameter of wire is 2.0 cm.
Explanation:
Substitute the known values in the expression of magnetic field to calculate the strength of the magnetic field at the center of the loop.
