The space surrounding a magnet is permeated by a __**magnetic field**__

creates a magnetic field that closely resembles the magnetic field produced by a circular loop of current-carrying wire

**permanent bar magnet**

magnetic force on a moving charge formula

magnetic force on a moving charge with magnitude formula

magnetic force on a current-carrying wire formula 

magnetic force on a current-carrying wire with magnitude formula

**Solenoid**

a device constructed by a series of coaxial wires through which a continuous current flows.

permeability of free space’s value

**tesla**

(abbreviated T) the SI unit for the magnetic field

What is the direction of force acting on the current-carrying wire as shown?

**Out of the page**

If the charged particle’s velocity is parallel (or anti-parallel) to the magnetic field lines, then _______________________________________________.

the particle will feel no magnetic force.

**Magnetic fields**

are created by moving charges

**Current carrying wires**

produce fields which are circles around the wire.

The direction of the field is found from the ___________________.

**right-hand rule**

To get the fields to cancel out at a location between the wires, they must carry current in the __________________.

**same direction**

Magnetic fields point from ___________________.

**north to south**

**Buoyant Force** is always perpendicular to ________.

**velocity**
