Physics 12 – Electromagnetism Questions
With Correct Answers 2026-2027
magnetic induction - CORRECT ANSWER -the creating of an electrical current using a magnetic
field
- the extension of a magnetic field
electromagnet demo - CORRECT ANSWER -- increase magnet strength = large iron core
- more current = more coils
right hand rule and magnetic field - CORRECT ANSWER -thumb in direction of current (I) in a
wire and fingers curl in direction of magnetic field
magnetic flux - CORRECT ANSWER -the amount of magnetic field passing through a loop of wire
solenoid - CORRECT ANSWER -loop of a bunch of coils around a hollow core
magnetic declination - CORRECT ANSWER -number of degrees between the 2 poles (geographic
vs magnetic)
angle of dip - CORRECT ANSWER -angle between horizon + earth's magnetic field lines
magnetic field lines - CORRECT ANSWER -never cross and they don't like to be crowded
- if they are crowded repulsion occurs
north pole is actually a - CORRECT ANSWER -magnetic south pole
