Section 28.5 Challenge - Magnetic Field from Current

ARC*S 28.5.1. Magnetic Flux.

🔗

What is the magnetic flux through an equilateral triangle with side $60 \mathrm{~cm},$ long, whose plane makes a 60 degree angle with a uniform magnetic field of $0.33 \mathrm{~T}\text{?}$

🔗

ARC*S 28.5.2. Solenoid.

🔗

Consider the magnetic field created by an infinitely long solenoid with radius $R$ and $n$ coils per unit length carrying a steady clockwise current $I\text{.}$ Starting from the assumption that the magnetic field everywhere in space must point in either the positive or negative $z$-direction (parallel to the axis of the solenoid), use Ampere’s Law to determine the magnitude and direction of this magnetic field.

🔗

Hint.

You will need to choose Amperian Loops thoughtfully, and you may need more than one!

Subsubsection Metacognitive Reflection

🔗

Write a short paragraph discussing how a changing magnetic field can result in an induced current. As part of your description, highlight specific activities you completed this week.
