Unit 2 - Forces On Charged Particles Flashcards
What is a field?
A region where an object experiences a force without being touched
What is an electric field?
The region of space around a charge
What are the two types of electric field?
Radial & uniform
What does it mean if field lines are closer together?
The greater the force
Where do electric fields exist?
Around any object that is charged
What is electrical potential?
The amount of energy required to move a charge of one coulomb to a point within the field
What is potential difference?
The difference in electrical potential between two points
What is the name given to the area of space around a Magnet?
A magnetic Field
What field exists around a stationary charge?
Electric field
What field is created by a moving charge?
Magnetic field
What is used to determine the direction of field lines in a current carrying wire?
The left hand screw rule
What does the thumb represent in the left hand screw rule?
Direction of current
What does the fingers represent in the left hand screw rule?
The direction of magnetic field lines
What rule is used to determine the direction of force on a charged particle in a magnetic field?
