This chapter is critical for MDCAT students since it sets a base for the comprehension of electromagnetic fields, electromagnetic waves, and their application in technology. Our MDCAT Quiz for this chapter will test your knowledge of key concepts and equations, helping you prepare thoroughly for the exam.
Overview of Electromagnetism
Electromagnetism is the study of the interactions between electric currents and magnetic fields. The chapter introduces the idea of a magnetic field and its characteristics. A magnetic field arises due to moving electric charges, for example, when a current flows through a conductor. Students learn about the formation of a magnetic field around a current-carrying wire and how the strength of the magnetic field depends on factors like the current and the distance from the wire. The concept of right-hand thumb rule is introduced, which helps determine the direction of the magnetic field around a current-carrying conductor.
Magnetic Force on a Current-Carrying Conductor
The chapter proceeds to discuss how magnetic fields exert a force on current-carrying conductors. The magnetic force on a conductor depends upon the amount of current, the length of the conductor, and the strength of the magnetic field. The equation for calculating the magnetic force is discussed, and students will learn how to apply this to solve problems. The concept of the Lorentz force, which acts on charged particles in a magnetic field, is also introduced.
Ampere’s Circuital Law and Magnetic Field Due to a Current
One of the main discussions in the chapter is Ampere’s Circuital Law, which relates the magnetic field around a conductor to the current flowing through it. The law generalizes the right-hand thumb rule and makes it possible to calculate the magnetic fields for more complicated geometries. The students will also learn about the magnetic field produced by a current-carrying solenoid, behavior with respect to bar magnets, and defined north and south poles. The magnetic field inside a solenoid is uniform and can be controlled by varying either the number of turns or the current.
Electromagnetic Induction
The chapter also discusses electromagnetic induction, which explains how an electric current can be induced in a conductor due to a changing magnetic field. This is the principle on which electrical generators and transformers work. The chapter includes detailed discussions on Faraday’s law of induction and Lenz’s Law, explaining how the induced current opposes the change in magnetic flux. The concept of self-induction and mutual induction is also explored, which helps students understand the working of inductors and transformers.
