electromagnetism

Question 1

what direction does current always flow in with magnetic fields?

Answer 1

the direction of velocity

Question 2

if an electron is in a magnetic field, what direction will it flow?

Answer 2

opposite to velocity as current is the rate of flow of positive charge

Question 3

What do we know about the magnetic field inside a solenoid?

Answer 3

they’re uniform

Question 4

Explain how a solenoid produces a magnetic field

Answer 4

• when current flows through wire, a magnetic field is generated around each loop of wire
• the magnetic fields of individual loops combine to produce uniform magnetic fields inside the solenoid
• the field lines are parallel and closely spaced, indicating a strong and uniform magnetic field
