Magnetic Effect of Current and Magnetis1
... Q4. What would be the effect of replacing ordinary bulbs with CFLs? a. CFLs give less light than regular bulb hence room would be less bright b. CFLs use less electricity hence electric bill will be reduced c. CFLs produce more heat hence chances of fire will be increased Q5. A coil of insulated cop ...

... The observation that this effect is not just a principle but leads to a remarkably fast rotation is due to the large current generated by the almost short circuit and the large field strength of the magnet. The low friction between the point of the screw and the battery and between the magnet and th ...
