V. Change the sentences using conditional sentences and translate them

about its axis). 2. The current in the loop would be reversed in direction if (sliding

contacts and a split­ting commutator to be used.). 3. They would know the principle

upon which ammeters and voltmeters operate, if they (to know that of the motor).

4. The rotation of a permanent magnet would be restrained, if (a coil of fine copper

wire to be mounted between the two poles of it). 5. The restoring force would be

greater if (the coil to be turned from its equilibrium position). 6. The resultant

magnetic field between the coil and the magnet would be distorted, if (we increase the

current through the moving coil of an ammeter or voltmeter). 7. Very delicate

ammeters would have been used, if we (to have to measure very small currents). 8. We

should have used an electromagnet if we (to require a uniform field of great strength).

9. We should be able to define the mechanical force if we (to know the force exerted

by the magnetic induction upon the individual moving electrons within the

conductor). 10. We should have used an electroscope if we (to be to measure the

electrical potential of a charged body).
