Who's it for?
This chapter of our SAT Physics Tutoring Solution will benefit any student who is trying to learn about magnetism to prepare for the subject test. This resource can help students, including those who:
- Struggle with understanding magnetic forces and fields, poles and dipoles, electromagnetic induction, conductors and transformers, Faraday's law, Lenz's law or any other magnetism topic
- Have limited time for studying
- Want a cost effective way to supplement their science learning
- Prefer learning science visually
- Find themselves failing or close to failing their magnetism unit
- Cope with ADD or ADHD
- Want to excel on the SAT physics subject test
- Don't have access to their science teacher outside of class
Why it works:
- Engaging Tutors: We make learning about magnetism simple and fun.
- Cost Efficient: For less than 20% of the cost of a private tutor, you'll have unlimited access 24/7.
- Consistent High Quality: Unlike a live physics tutor, these video lessons are thoroughly reviewed.
- Convenient: Imagine a tutor as portable as your laptop, tablet or smartphone. Learn about magnetism on the go!
- Learn at Your Pace: You can pause and re-watch lessons as often as you'd like, until you master the material.
Learning Objectives
- Review magnetic force and properties of magnets.
- Understand what a magnetic field is and how it's created.
- Find out how moving charges are affected by magnetic forces.
- Learn the variables that affect electromagnetic induction.
- Study applications for Faraday's law and Lenz's law.
1. Magnetic Force: Definition, Poles & Dipoles
You're probably familiar with magnets, but have you ever stopped to consider how they work? In this lesson, we'll look at the root of magnetism and some of the fundamental properties of magnets.
2. What is a Magnetic Field?
Magnetic fields fill the space around all magnets, but they're impossible to detect with our own senses. We'll use a common tool to map out a magnetic field and then discuss ferromagnetic materials to see how a magnetic field can be used to create new magnets.
3. How Magnetic Fields Are Created
Have you ever wondered how magnetic fields are created? In this lesson, we'll discuss the very simple answer to this question and look at how electric current can be used to make electromagnets, which have many everyday applications.
4. How Magnetic Forces Affect Moving Charges
A magnetic field exerts a force on a moving charged particle in ways that you might not expect. In this lesson, we're going to look at the direction of this force and the factors that affect its strength.
5. Electromagnetic Induction: Definition & Variables that Affect Induction
We use electromagnetic induction every day, but do you have any idea what it is? In this lesson, we'll discuss this everyday phenomenon, the factors that affect its strength and its most common applications.
6. Electromagnetic Induction: Conductor to Conductor & Transformers
Every day, we make use of a special case of electromagnetic induction known as mutual induction. In this lesson, we'll talk about this special phenomenon and how it is used in many common devices.
