What is an electrical property of matter that creates electric and magnetic forces and interaction?
The property is called charge, which is a fundamental property of matter that can be positive or negative. Charged particles create electric fields that exert forces on other charged particles, while moving charged particles create magnetic fields that can also exert forces on other charged particles. The interaction between electric and magnetic fields is known as electromagnetism.

What is the difference between electrical force and charge?
Electric force is the force exerted between charged particles, while charge is a fundamental property of matter that determines how particles interact with electric and magnetic fields. In other words, charge is the property that gives rise to electric force.
What are the key differences between electromagnetism and magnetism?
Electromagnetism involves the interaction between electric currents and magnetic fields, while magnetism is the property of certain materials to attract or repel each other. Electromagnetism can be turned on and off by controlling the flow of electric current, whereas magnetism is a constant property of certain materials.
What is the difference between magnetism and electromagnetism?
Magnetism is a natural force produced by certain materials, while electromagnetism is the interaction between electric currents and magnetic fields. In other words, magnetism is a property of materials, while electromagnetism involves the flow of electric current.
Why are speakers magnetic and how does this property contribute to their functionality?
Speakers are magnetic because they contain a magnet that interacts with an electrical current to create sound. This property allows the magnet to move a diaphragm, which produces sound waves that we hear as audio. In essence, the magnetic property of speakers is essential for converting electrical signals into sound waves, making them functional devices for audio output.
What is the Difference between reluctance and resistivity?
Resistivity is the intrinsic property of a conductor, and it is independent of the size of that conductor. Resistance is an extrinsic property that makes it dependent upon the amount of the material that there is present.

How electric current causes magnetic field around conductor?
When an electric current flows through a conductor, it creates a magnetic field around the conductor. This is due to the interaction between the moving charges (the electrons in the current) and the magnetic fields they produce. The magnetic field strength is directly proportional to the current flowing through the conductor.

What is electomagnetisam?
Electromagnetism is the physics of theelectromagnetic field, a field that exerts a force on particles with the property of electric charge and is reciprocally affected by the presence and motion of such particles. A changingmagnetic field produces an electric field(this is the phenomenon of electromagnetic induction, the basis of operation for electrical generators, induction motors, andtransformers). Similarly, a changing electric field generates a magnetic field. The magnetic field is produced by the motion of electric charges, i.e., electric current. The magnetic field causes the magnetic force associated with magnets. The theoretical implications of electromagnetism led to the development ofspecial relativity by Albert Einstein in 1905; and from this it was shown that magnetic fields and electric fields are convertible with relative motion as a four vector and this led to their unification as electromagnetism.
What is magnetoresistence?
The change in electrical resistance produced in a current carrying conductor or semiconductor on application of magnetic field H.
What is the Difference between reluctance and resistivity?
Resistivity is the intrinsic property of a conductor, and it is independent of the size of that conductor. Resistance is an extrinsic property that makes it dependent upon the amount of the material that there is present.
What property makes electric motor possible?
Magnetism. The ATTRACTION and REPULSION of magnetic poles is the BASIC design process that makes electric motors work.
What light is classified because electrical and magnetic fields vibrate in a light wave?
Polarized light is classified based on the orientation of its electric and magnetic fields in the light wave. This property is used in applications such as 3D movie glasses and glare reduction sunglasses to filter out specific orientations of light waves.
What is the property of light that allows it to travel at that speed?
The speed of light is determined by the electric and magnetic properties of the stuff it's traveling through. The "light" itself is just electrostatic and magnetic fields traveling together through the stuff. Change the electrical properties of the medium, and you change the speed of light through it.
