A student designed an experiment to test the effect on the magnitude of the magnetic field that is generated around the wire loo
p. The student increased the current that passes through the wire and tests the magnitude of the magnetic force that is generated. The experimental setup is shown here. Which statements accurately describe this experimental design? Select ALL that apply. A) The student's dependent variable is the size of the wire loop. B) The student's independent variable is the size of the wire loop. C) The student's dependent variable is the magnitude of the magnetic field that is generated. D) The student's independent variable is the magnitude of the magnetic field that is generated. E) The student's independent variable is the amount of current that is being passed through the wire.
He was the first scientist to observe and describe bacteria and protozoa by looking at a drop of water from a pound under a microscope. He also was the one to build the first compound microscope.
