Answer my question Master of phipsiesCh34. To obtain maximun induced c.mf, jn dypamo's coil, the plane of the commust be;a) Normal to the magnetic fieldb) Parallel to the magnetic fieldc) Inclined by an angle 30 to the magnetic fieldd) Inclined by an angle 60 to the magnetic field. The electrie cunent intenslty flowing through an inductive coll becomessteady after a certain time due to:a) The effect of self inductionb) The generation of electric currentsc) The presence of eddy currentsd) The stability of magnetic flux lines around the ooil6- The curent flowing through the primary coil of the transformer vanishesalthough it is coenected to the electric source, when no current is taken fromits secondary coil, due to:a) The effect of self induction of the primary coilb) The generation of eddy currentsc) The increase of its number of tumsd) The effect of the mutual inducation7- la the calibrated resistors the wires are double wounded:a) To decrease the eddy currentsb) To increase the resistance of the coilc) To cancel the effect of self inductiond) To increase the murual indaction8- At the moment of starting flowing the electric current in primary coil inside a-secondary one. The induced current in the secondary coil is:a) Forward curent Master of physiesCh3Questions for the self-evaluation student'n golde,Fist: Multiple cholce queetions1- The diagram shows a wire carrying a cutrent between ithe poles of amagnet.
