In an electric motor periodically changing the direction of current in the electromagnetic can cause the axle to spin because?
In an electric motor, periodically changing the direction of current in the electromagnet causes the magnetic field to alternate. This changing magnetic field interacts with the permanent magnets on the rotor, creating a rotational force that causes the axle to spin. This process is known as electromagnetic induction.

How does alternating current create an electromagnetic field?
Alternating current creates an electromagnetic field through the flow of electric charge that changes direction periodically. This changing current induces a changing magnetic field, which in turn generates an electromagnetic field around the conductor.
What is the relationship between electromagnetic waves and vibrations?
Electromagnetic waves are created by vibrating electric charges. When an electric charge oscillates, it creates a changing electric field which in turn generates a changing magnetic field. This interplay of changing electric and magnetic fields propagates through space as electromagnetic waves.
What is the direction of propagation of an electromagnetic wave?
An electromagnetic wave propagates in a direction perpendicular to both the electric and magnetic fields.
Why is a vibrating electric field an example of an electromagnetic wave?
A vibrating electric field produces a changing magnetic field, which then generates a changing electric field and so on, creating a self-propagating wave. This wave consists of oscillating electric and magnetic fields perpendicular to each other and to the direction of wave propagation, thus exhibiting the characteristics of an electromagnetic wave.
How are elctromagnatic waves generated?
Electromagnetic waves are generated by accelerating electric charges. When an electric charge is accelerated, it creates a changing electric field which, in turn, generates a changing magnetic field. These changing electric and magnetic fields propagate through space as electromagnetic waves.

How does a changing magnetic field produce an electric field according to electromagnetic theory?
According to electromagnetic theory, a changing magnetic field induces an electric field. This phenomenon is known as electromagnetic induction, where the changing magnetic field creates a force that causes electrons to move, generating an electric current.
What causes a electromagnetic wave?
An electromagnetic wave is caused by the vibration of electric and magnetic fields propagating through space. When an electric charge accelerates, it creates a changing electric field, which in turn generates a magnetic field. The changing magnetic field then creates a changing electric field, and this cyclical process results in the formation of an electromagnetic wave.
What consists of changing electric and magnetic field s?
Changing electric and magnetic fields consist of producing electric currents, electromagnetic waves, or inducing magnetic fields in a given medium. This change can be observed through various phenomena, such as electromagnetic induction, electromagnetic radiation, or the propagation of electromagnetic waves.
How are electric charges related to electromagnetic waves?
Electric charges are at the heart of electromagnetic waves. When an electric charge accelerates or changes its motion, it produces a changing electric field, which in turn generates a changing magnetic field. These interacting electric and magnetic fields propagate through space as electromagnetic waves, carrying energy and information.
What transverse waves disturb electromagnetic fields?
Electromagnetic waves, such as light and radio waves, are transverse waves that disturb electromagnetic fields. The changing electric and magnetic fields of these waves propagate perpendicular to the direction of wave motion.
What do electromagnetic travel through?
changing electric and magnetic fields {[((apex))]}
How electro magnetic produced?
Electromagnetic waves are produced by the acceleration of electric charges. When an electric charge is accelerated, it creates a changing electric field, which in turn produces a changing magnetic field. These changing electric and magnetic fields interact with each other, resulting in the generation of electromagnetic waves that propagate through space.
