Electric Force and Magnetic Field Effects

These flashcards cover key concepts and terms related to electric force, magnetic fields, and related measurements as discussed in the lecture.

Magnetic Force

The force exerted on a current-carrying wire in a magnetic field.

Electric Field (E)

A field around charged particles that exerts a force on other charged particles.

Test Charge (q)

A charge used to measure the electric field strength at a point.

Magnetic Field (B)

A vector field that exerts magnetic forces on moving charges and current-carrying wires.

Magnitude of Magnetic Force (FB)

Given by the formula FB = ILBsin(θ), where I is the current, L is the length of the wire in the field, and B is the magnetic field strength.

Net Force (Fnet)

The total force acting on an object, calculated from the sum of all individual forces.

Test Charge Measurement

The measurement of electric forces acting on a single test charge.

Current (I)

The flow of electric charge, measured in amperes (A).

Weight (W)

The force exerted by gravity on an object, calculated as W = mg, with m being mass and g being gravitational acceleration.

Length of Wire (L)

The physical extent of the wire that is in the magnetic field, crucial for calculating magnetic force.
