3 cards from this section. Quick, good the night before a test.
What is the equation for the force on a straight conductor carrying current in a magnetic field?
Recall the relationship of current, magnetic field, and length.
What does the right-hand rule help determine?
Use your right hand to visualize the directions of current and field.
What is the formula for the magnetic force on a current-carrying conductor?
Remember the context of current in a magnetic field.
True or False: The magnetic force on a conductor is always parallel to the current direction.
Use the right-hand rule to recall the force's direction.
Calculate the force on a 1.5 m wire carrying a current of 10 A in a magnetic field of 0.8 T at an angle of 30° to the field.
Use the sine function for the angle to calculate force.
A wire of length 2 m carries a current of 5 A and is placed at 45° in a magnetic field of 0.6 T. Determine the force on the wire.
Remember to calculate sin(45°) and use it in your calculations.
