9. Electromagnetism Flashcards
1
Q
What is the Electric Field Strength
A
It is the electric force exterted per unit positive charge acting on a small stationary charge placed at that point
2
Q
What is an Electric Field
A
It is the region of space where a stationary charge experiences a force. The direction of the electric field is the direction of the force on a positive charge
3
Q
What is a Magnetic Field
A
It is a region of space in where a magnetic pole, a current-carrying conductor or a moving charged particle will experience a force
4
Q
What is a Magnetic Flux Density
A
It is the force acting per unit length on a straight wire which carries a unite current and is at a right angle to the direction of the magnetic field
