The force on a wire that carries electricity in a magnetic field is really cool and interesting! Let’s break it down:

1. Magnetic Field Direction: The force depends on which way the magnetic field is pointing. There’s a handy trick called the right-hand rule. To use it, point your thumb in the direction that the electric current is flowing. Then, curl your fingers in the direction of the magnetic field. The direction your palm faces shows the direction of the force.

2. Magnitude of the Force: We can figure out how strong the force is using a simple formula:
   $F = BIL \sin(\theta)$
   Here’s what the letters mean:

   • $B$ is how strong the magnetic field is,
   • $I$ is the electric current,
   • $L$ is how long the wire is in the magnetic field, and
   • $\theta$ is the angle between the wire and the magnetic field.

3. Increasing Factors: If you want to make the force stronger, you can do a few things:

   • Increase the electric current ($I$),
   • Use a stronger magnetic field ($B$), or
   • Change the angle ($\theta$) to be 90 degrees for the best effect.

It’s all about how electricity and magnetism work together!
