Magnetic Fields Flashcards
All 5 cards in this deck
In which direction do magnetic field lines point outside a magnet?
From the north pole to the south pole.
Where is the magnetic field around a bar magnet strongest?
At (close to) the poles, where the field lines are closest together.
Describe the magnetic field lines of the uniform field between the north pole of one magnet and the south pole of another facing it.
Straight, parallel, equally spaced lines going from the north pole to the south pole.
What are the steps to use plotting compasses to show the shape and direction of the field around a bar magnet?
e.g. a bar magnet on a sheet of paper- Place a compass near the magnet and mark the direction the needle points with dots.
- Move the compass to various positions and plot more points.
- Join the dots to give several field lines, with arrows from north to south.
What is a uniform magnetic field?
A magnetic field that has the same strength and the same direction at every point.
