All Flashcards
What is the effect of a charged particle moving perpendicular to a uniform magnetic field?
The particle undergoes cyclotron motion, moving in a circular path.
What happens to the magnetic field strength as you move further away from a long, straight current-carrying wire?
The magnetic field strength decreases.
What happens when the angle between a current-carrying wire and a magnetic field is 90 degrees?
The force on the wire is maximized.
What is the effect of increasing the current in a long, straight wire?
The magnetic field strength around the wire increases.
What happens when a charged particle enters a uniform magnetic field perpendicular to its velocity?
The particle undergoes cyclotron motion, moving in a circle.
What is the effect of orienting a current-carrying wire parallel to a magnetic field?
The magnetic force on the wire is zero.
What is the effect of increasing the distance from a current-carrying wire?
The magnetic field strength decreases.
What happens when the angle between a wire and a magnetic field increases from 30 to 90 degrees?
The magnetic force on the wire increases.
What is the effect of breaking a bar magnet in half?
You get two smaller bar magnets, each with its own north and south pole.
What happens when like poles of magnets are brought together?
They repel each other.
What happens when opposite poles of magnets are brought together?
They attract each other.
What is the effect of an external magnetic field on a magnetic compass?
The compass aligns itself with the external magnetic field.
What is the effect of temperature on the permeability of a material?
Permeability can change with temperature.
What is the effect of increasing the density of magnetic field lines?
The strength of the magnetic field increases.
