Module 6.3 - Electromagnetism Flashcards
1
Q
Define magnetic field
A
The region around a permanent magnet or a moving charge in which another body with magnetic properties will feel a force
2
Q
Magnetic field lines
A
Show the shape and direction of the field
Direction of the field line at a point shows the direction in which a plotting compass would point
3
Q
What is a solenoid?
A
Long coil of current-carrying wire
4
Q
Define magnetic flux
A
Product of magnetic flux density and the area at right angles to the flux
Measured in webers
5
Q
Define magnetic flux density
A
Measure of the strength of the magnetic field
6
Q
Define one weber
A
The magnetic flux when a magnetic field of magnetic flux density one tesla passes at right angles through an area of one square metre
