Lesson: Magnetic Flux High School Physics

Physics

In this lesson, we will learn how to determine the magnetic flux through a loop in a magnetic field and recognise changes in the magnetic flux through a loop.

Worksheet

Q1:

A rectangular coil of wire has sides of lengths 25 cm and 45 cm. The coil is placed into a magnetic field of 0.35 T. All the sides of the turns of the coil are perpendicular to the direction of the field. The flux linkage of the coil is 1.55 Wb. How many turns are in the coil? Round your answer to the nearest whole number of turns.

Q2:

Two identical loops of conducting wire are in a uniform magnetic field, as shown in the diagram. How does the magnetic flux through both loops compare?

Q3:

A rectangular coil of wire has sides of lengths 35 cm and 55 cm. The coil contains 50 turns. The coil is placed into a magnetic field of 0.15 T. All the sides of the turns of the coil are perpendicular to the direction of the field. What is the flux linkage of the coil?
