Magnetic Fields and Forces: The Basics (VCE SSCE Physics): Flashcards

Object that attracts iron, nickel, and cobalt

Regions where magnetic effect is strongest

Combination of a north pole and a south pole

$B$, measured in tesla ($\text{T}$)

From north pole to south pole

Indicates field strength (close = strong, apart = weak)

Creates its own magnetic field around the wire

Thumb = current direction, fingers = field direction

Coil of wire with many loops wound closely together

Solenoid with an iron or steel core inside
