Parts a through f of Figure Q25.3 show one or more metal wires sliding on fixed metal rails in a magnetic field.
Parts a through f of Figure Q25.3 show one or more metal wires sliding on fixed metal rails in a magnetic field. For each, determine if the induced current is clockwise, counterclockwise, or is zero.
The metal equilateral triangle in the figure, 20 cm on each side, is halfway into a 0.1 T magnetic field.
A) What is the magnetic flux through the triangle?
B) If the magnetic field strength decreases, what is the direction of the induced current in the triangle?
