A straight wire carries a current of 3 A. Using the Right-Hand Grip Rule, describe the direction of the magnetic field 10 cm away from the wire.
💡 Hint: Use your right hand to see which way to curl your fingers!
If you have a solenoid with 200 turns and a current of 5 A, and you bend it into a circular shape, how will the strength of the magnetic field compare to a single straight wire?
💡 Hint: Think about how many wires you are essentially adding together.
