Summary

Electromagnetism is a critical component of physics, playing a pivotal role in everything from circuits to medical imaging technologies like MRIs. It is also a crucial topic for the MCAT, appearing frequently in the physics and chemistry sections.

In this episode, Sam Smith breaks down the fundamental concepts of electricity and magnetism. Sam walks through the basics of static electricity, charge conservation, and Coulomb’s Law and explains how moving charges create currents and the forces exerted by electric and magnetic fields.

0:00.0	Welcome to MCAT Basics, your ultimate guide to the essential topics you need to master for the MCAT,
0:07.2	brought to you by the physicians at Med School Coach.
0:11.0	Every week, Sam Smith breaks down high-yield MCAT topics, ensuring you're primed for success on test day.
0:17.0	Join Sam as we explore the most crucial subjects outlined by the AAMC, pulled from official practice materials and third-party resources.
0:25.5	Get ready to elevate your MCAT game with topics tailored to maximize your score potential.
0:30.7	Hello, I'm Sam Smith.
0:33.8	This podcast is going to cover electricity and magnetism, which is the theory that underlies one of the most important physics topics on the MCAT, which is circuits.
0:44.7	And a podcast about circuits is going to be a whole podcast on its own.
0:48.3	This one's just going to talk about electricity and magnetism, because it's still a pretty important topic to understand for the MCAT.
0:54.8	You will see at least a few questions about either electricity or magnetism or both.
1:01.0	So still an important topic.
1:02.5	Don't ride it off.
1:03.8	And the bulk of this material will be found on the physics and chemistry section of the
1:09.6	MCAT.
1:10.1	So it's one out of the four.
1:11.5	You might see some of this on also the bio-biochem,
1:15.5	you know, just maybe a little bit of a circuit topic or something like that.
1:18.9	But mainly it's going to be focused on the chemistry and physics portion of the MCAT.
1:23.6	So without further ado, let's get into electricity and magnetism.
1:33.0	So let's talk first about electricity.
1:35.8	The first thing to understand about electricity is charge.
1:39.2	First of all, what is charge?
	...
