- Induced EMF Below is a closed conducting loop within a magnetic field (for direction see picture). The loop is a circle with a radius of r = 5.00 cm. The magnetic field is decreasing in the direction shown at a rate of dB/dt = 157.0 mT/s. The circle wire has 305.0 loops around it. The wire has a total resistance of R = 2.80 Ohms. Magnetic Field (into the page) 8) What is the induced current around the wire in this system? (use a negative value for a clockwise current) Make sure to give your answer in an appropriate number of significant figures as well as including units with your answer.
