Find (a) Stored Energy inside this coil. (b) Magnetic Energy Density. (c) Find voltage across the coil if electric current increases from 12.0A to 18.0A in 6.0 m.sec.The magnetic flux through the loop increases according to the relation shown below. What is the magnitude of the induced emf in the loop when t = 3.0 s
- 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. Your Answer: Answer units PLEASE TAKE OUT TRASH AT EOS IGO Resources Give Up O Hint A 145 turn circular coil of radius 2.29 cm is immersed in a uniform magnetic field that is perpendicular to the plane of the coil. Over an interval of 0.169 s, the magnetic field strength increases from 55.7 mT to 99.3 mT. Find the magnitude of the average emf Eve induced in the coil during this time interval, in millivolts. Eve = mVA 2-turn planer loop of flexible wire is placed inside a long solenoid of n turns per meter that carries a constant current I0 . The area A of the loop is changed by pulling on its sides while ensuring that the plane of the loop always remains perpendicular to the axis of the solenoid.
