Answer from: electrofy456

Electric field is associates to each point in space as a electric force per unit of charge.

Magnetic field is defined as the vector field necessary to make the Lorentz force correctly.

Explanation:

The electric and magnetic fields are both manifestations of the electromagnetic force.

For instance, the electric field is associates to each point in space as an electric force per unit of charge.Now, the magnetic field is defined as the vector field necessary to make the Lorentz force law correctly describe the motion of a charged particle.

Let's recall that the magnetic force is described by the Lorentz Force. It means the attraction or repulsion that arises between electrically charged particles because of their motion.

I hope it helps you!

Answer from: Anybody6153

see explanation

Explanation:

- Electric field is a point value in space that is generated by charge placed in space which exerts an electric force per unit of charge. As per Coulomb's Law:

E = Fe / q

- Magnetic field is generated by a magnetic or a source of moving charges in a region of space that allows attraction towards the source. The formulation is given as Lorentz force (Fm)

Fm = q* ( v x B )

- Lorentz Force can either by attractive or repulsive that arises between electrically charged particles because of their motion.

- Electric Force can either by attractive or repulsive that arises between two charged particles depending on the signs of charge on each.

"i have always loved contemporary art and made it a general goal to work within the field. after a few nonprofit internships at museums and galleries, i decided to try the for-profit art world and was offered a job as the ad assistant at the magazine. i much prefer the pace of the for-profit art community and have stayed with the company for three years, with a promotion to an account manager last spring."

i just did this and got a 100.

Clothing made of several thin layers of fabric with trapped air in between, often called ski clothing, is commonly used in cold climates because it is light, fashionable, and a very effective thermal insulator. so it is no surprise that such clothing has largely replaced thickand heavy old-fashioned coats. (a) consider a jacket made of five layers of 0.1-mm-thick synthetic fabric (k = 0.13 w/m·°c) with 1.5-mm-thick air space (k = 0.026 w/m·°c) between the layers. assuming the inner surface temperature of the jacket to be 28°c and the surface area to be 1.25 m2, determine the rate of heat loss through the jacket when the temperature of the outdoors is 0°c and the heat transfer coefficient at the outer surface is 25 w/m2·°c. (b) what would your response be if the jacket is made of a single layer of 0.5-mm-thick synthetic fabric? what should be the thickness of a wool fabric (k = 0.035 w/m·°c) if the person is to achieve the same level of thermal comfort wearing a thick wool coat instead of a five-layer ski jacket?
