What does the Right-Hand Rule help you determine?
Think about how you position your thumb and fingers.
True or False: The Right-Hand Rule can be used for both electrical circuits and magnetism.
Remember, it relates to how current flows and magnetic fields interact.
Which direction does the thumb point in the Right-Hand Rule?
Remember the positioning of your hand.
True or False: The Right-Hand Rule can only be used for straight conductors.
Consider applications in motors and coils.
A current of 5 A flows through a wire placed in a magnetic field of 0.2 T. If the angle between the wire and the magnetic field is 90 degrees, calculate the force on a 2-meter length of the wire.
Remember to input the known values cleverly into the formula.
A wire carrying a current is subjected to a magnetic field directed to the west. If the wire is oriented north, what direction will the force act if the current flows south?
Draw it out if you must to visualize the interactions.
