Students in a Physics class are conducting experiment to know how to increase the strength of an electro magnet. (9b) Student 1- Place another nail with the first and reduce the number of coils
Student 2- use a wooden splint instead of nail and add few more coils around the splint.
Student 3- Remove the nail and connect both ends of the coil to the same battery terminal.
Student 4- add additional wraps around the nail and add another battery to increase the current through the wire. Which student described the steps correctly?
