Introduction
This unit covers Electricity and Magnetism within the context of the MCAT Physics section. The 19 topics in this unit span foundational concepts and high-yield material that appear regularly on the exam.
The unit includes the following major topic areas: Capacitance, Coulomb law, Current, Dielectrics, Electric charge, Electric field, Electric potential, Electromagnetic induction, Faraday law, Kirchhoff laws, Lenz law, Magnetic fields, and 7 additional topics.
Key concepts from the highest-yield topics include:
Magnetic force: Magnetic force is a fundamental concept in Physics that describes the force exerted on moving charged particles or current-carrying conductors when placed in a magnetic field. This topic sits at the intersection of Electricity and Magnetism, two domains that are intimately connected thro
Parallel circuits: Parallel circuits represent one of the two fundamental ways electrical components can be connected in a circuit, alongside series circuits. In a parallel circuit, components are connected across common points or junctions, creating multiple pathways for current to flow. This configuration is ubi
Power in circuits: Power in circuits is a fundamental concept in Electricity and Magnetism that describes the rate at which electrical energy is converted into other forms of energy - such as heat, light, or mechanical work - within an electrical circuit. Understanding power relationships is essential for analyzin

Study Strategy
Approach Electricity and Magnetism systematically by building from foundational to advanced concepts:
- Foundation First: Master the basic definitions and core concepts before moving to application-level material.
- High-Yield Priority: Of the 19 topics, the 4 high-importance topics should receive the most study time.
- Active Recall: Use the FAQ questions in each topic to test your retention before moving on.
- Passage Integration: Practice applying these concepts to MCAT-style passages, which often require synthesis across multiple topics.
- Cross-Topic Connections: Look for links between topics within Electricity and Magnetism and connections to other Physics units.
For complex topics like Parallel circuits, create concept maps linking related terms. Visual organization helps consolidate the dense vocabulary found in Electricity and Magnetism.
Common Mistakes
Students frequently lose points on Electricity and Magnetism questions due to these recurring errors:
- Confusing similar-sounding terms or processes within Electricity and Magnetism
- Applying concepts from one topic to situations that require knowledge from a different topic
- Overlooking the direction or sign conventions in quantitative Electricity and Magnetism problems
- Missing the clinical or physiological significance of Electricity and Magnetism concepts
A common error in Electricity and Magnetism is memorizing isolated facts without understanding the underlying mechanisms. MCAT questions often test whether you can apply a concept to a novel scenario, not just recall a definition.
Exam Tips
Use these strategies when encountering Electricity and Magnetism questions on the MCAT:
- Read the entire passage before answering questions; Electricity and Magnetism passages often contain data tables or figures that are essential for answering questions correctly.
- For discrete questions on Electricity and Magnetism, eliminate answer choices that conflict with fundamental principles before selecting the best answer.
- When a question presents an unfamiliar scenario, map it back to core Electricity and Magnetism concepts you know.
- Pay attention to experimental design questions involving Electricity and Magnetism topics, as these are increasingly common on the MCAT.
- Review any Electricity and Magnetism topics that overlap with Physics material from other units, as cross-unit synthesis is frequently tested.
