- A 140-turn circular coil has diameter 4.5 cm. A magnetic field perpendicular to the coil is changing at 0.80 T/s. What is the induced emf in the coil? The symbology is what is killing me. I don't understand the logic steps or where you have to substitute values to determiine the emf.In the figure, a 140-turn coil of radius 3.3 cm and resistance 6.9 Q is coaxial with a solenoid of 240 turns/cm and diameter 4.1 cm. The solenoid current drops from 1.7 A to zero in time interval At = 28 ms. What current is induced in amperes in the coil during At? Coil Solenoid Number i UnitsThe switch S in the circuit has just been closed. Right after (at t= 0) the current shown is measured to be / = 6 A. Determine the induced voltage Vbs = V- Va in the inductor (in Volts) at !! this moment. S. 50 0 200 V 500 15 mH ww -ww0000
- As shown below, a wire loop with a radius of 0.84 m is immersed in a B-field (the direction of the field is shown in the diagram). The B-field decreases from 10 T to 6 T and as a result a 8 V voltage & a 8.1 A current are induced. Determine how long the B-field was changing & the loop's resistance. At = the loop's resistance = ΩTwo coils are placed close together in a physics lab to demonstrate Faraday's law of induction. A current of 8.00 A in one is switched off in 2.00 ms, inducing a 3.00 V emf in the other. What is their mutual inductance (in mH)? mH Additional Materials Reading
