Instead of magnetic current you should write voltage.all other filling seems right
I want to insert some more basic idea about (not directly related to your question) Faraday's law that if magnetic field passing through a loop changes uniformly induced emf will be constant .and if changes non uniformly it will not remain constant

Question 1 Select the correct answer(s): When considering electromagnetic induction, Lenz's Law determines the magnitude of the emf induced across the ends of a coil of wire that is rotating in a magnetic field. The smaller the change in magnetic flux, the greater the induced emf. Faraday's Law can be used to calculate the magnitude of an induced emf. Electric current can be induced by a changing magnetic field. Submit Answer Tries 0/3

Moving charges will produce a local magnetic field, but the reverse is also true a changing magnetic field will similarly induce charges to move (ie. produce current). Consider a magnet moving into a coil of wire: A spinal coil of wire with many closely-spaced tums this is called a solenoid is connected to a micro-ammeter as shown in the diagram above. As the magnet moves into the coil, any induced current will be measured by the micro-ammeter. Question On the...
