Astudent designs an electromagnet, as shown in the picture. the electromagnet is only able to pick up 1 paper clip. list 2 modifications he could make to his electromagnet in order to enable it to pick up more paper clips.

Answer:

1. The student could increase the number of loops of wire around the iron core. Increasing the number of windings will increase the strength of the electromagnet also known as the magnetomotive force.

2. The student could use a bigger battery so that the voltage is increased. Thus, according to Ampere's Law, the magnetic field around the current-carrying wire will also increase as it is directly proportional to the current's strength.

the oxygenated blood then leaves the lungs through pulmonary veins, which return it to the left heart, completing the pulmonary cycle. this blood then enters the left atrium, which pumps it through the mitral valve into the left ventricle. from the left ventricle, the blood passes through the aortic valve to the aorta.

deoxygenated blood leaves through the right ventricle through the pulmonary artery. from the right atrium, the blood is pumped through the tricuspid valve (or right atrioventricular valve), into the right ventricle.
