What happens to a current-carrying conductor in a magnetic field?
Think about the interaction between electricity and magnetism.
What is the right-hand rule used for?
Use your right hand to visualize the current and magnetic field.
What is the formula for calculating the force on a current-carrying conductor?
Remember the variables in the equation.
True or False: The force on a conductor in a magnetic field is always directed along the magnetic field.
Use the right-hand rule to visualize the directions.
A wire of length 2 meters carries a current of 3 A in a magnetic field of strength 0.4 T. Determine the force on the wire if it is perpendicular to the field.
Apply the formula for force on a conductor.
If the same wire carried 5 A of current and the magnetic field direction was angled at 30° to the wire, find the effective force on the wire.
Remember to use the sine of the angle for the force calculation.
