A negatively charged object is placed within a positive electric field. what happens to the object?
Electric Field between positive and negative charges. If the Electric Field in which both the positive and negative charges are present is stronger than the Electric Field between the two charges we are talking about, the the negative charge will move away from the positive charge in that positive direction of the field. If not, then the negative charge will get attracted to the positive charge and stay at the position of the positive charge. It will be pulled toward the source of the electric field. (Novanet)
Who discovered electromagnetic force?
Hans Orsted first discovered that when an electric current was run through a wire and put close to a compass, the needle moved toward it. Although, he had no idea what that meant. Michael Faraday, built on his work and found that when an electric current runs through a wire, a magnetic field is produced around the wire. He also found that an electric field is around a wire it produces an electric current. The direction of the current depends on which direction the field is going in. The faster you move the electric field the stronger the current.
What type of magnetic field will produce an electric current in a wire?
A current carrying wire has a magnetic field around it but no electric field.There will be electric field around a body only if it has static electricity.In this wire, charges(electrons) are moving.The number of charges entering is equal to number of charges leaving the conductor.So it remains neutral.A neutral body cannot have an electric field around it. ACTUALLY, there IS also an electric field. A current is made up of moving charges, and all charges (moving or static) create an electric field. Materials that have a neutral charge are not good conductors and therefore would not have a current going through them in the first place.
Describe how a simple generator produces electric energy?
A copper wire coil is rotated at speed in a magnetic field, to cause electrons to move. This is the electric current. The stronger the magnets and/or thicker the copper coil, the more current is produced
Is gamma radiation stopped by an electric field?
No, gamma rays are not stopped by an electric field.
Gets stronger as you get closer to an electric charge?
The electric field gets stronger as you get closer to an electric charge.
What electric field gets stronger as you?
One that is powered by your own strength. If you want the field to get stronger, spend more time at the gym.
Is it true or false that an electric field gets stronger the closer it is to the charge?
True. The strength of an electrical field follows an inverse square law.
What do lines represent in an electirc field diagram?
The lines in each diagram represent an electric field. The stronger the field, the close together the lines are.
What do lines represent in an electric field diagram?
The lines in each diagram represent an electric field. The stronger the field, the close together the lines are.
What happens to a magnetic field when you add multiple magnets?
The field gets stronger
What happens to the electric field when you get farther from an electric charge?
An electric field gets stronger the closer you get to a charge exerting that field. Distance and field strength are inversely proportional. When distance is increased, field strength decreases. The opposite is true as well. Additionally, field strength varies as the inverse square of the distance between the charge and the observer. Double the distance and you will find that there is 1/22 or 1/4th the electric field strength as there was at the start of your experiment.
Is the electric field caused by an electron weakest near the electron?
The electric field is stronger near the electron and becomes weaker as the distance from the electron increases.
Is it True or false the greater the distance the stronger the electric field?
It is false.
What happens when a electric current is passed through a coil of wires?
You generate a (stronger) magnetic field.
How could you produce a magnetic field using a wire?
Any time an electric current passes through a wire, this will produce a magnetic field. If you want to make the field stronger, loop the wire into coils. The more coils you make, the stronger the field will be.
Is the greater the distance from a charged object the stronger the electronic field?
No, the strength of the electric field decreases with distance from a charged object. The electric field follows an inverse-square law, meaning it decreases with the square of the distance from the source charge. So, the closer you are to the charged object, the stronger the electric field.
