A wire with current flowing through it produces a magnetic field around it according to Ampere's law. The direction of this magnetic field is determined by the right-hand rule. The strength of the magnetic field is directly proportional to the current in the wire and inversely proportional to the distance from the wire.
What else can I help you with?
Can a solenoid suspended by a string be used as a compass?
A solenoid can be used as a compass when a DC current is going through it because when a current is going through the solenoid, the magnetic field lines are nearly uniform and perfectly parallel inside of it, giving it essentially a north pole and south pole.
How do you make an elctro magnet stronger?
To make a magnet more powerful you need to simply increase the flow of elctric charge going through it. For example if you connect some copper wire ina circuit and coil it around the magnet, the more coils = the more electrically charged particles = the magnetism is increased. A simple name for this is and elctro-magnet.
What does an ameter do in a circuit?
An Ammeter provides a visual display of the magnitude of the current flowing through it. Ideally, the ammeter does nothing "in the circuit". You don't want your test equipment to change anything going on in the circuit you're measuring.
Can electromagnets be turned on and off easily?
Yes.Electromagnets turn on when an electrical current is sent through the wiring wrapped round the iron core. It ceases to be magnetised when the current is turned off.
What is the difference between series and parallel circut?
If two or more circuit elements are connected in series, the current must pass through each of them in turn. If two or more circuit elements are connected in parallel, that means there is a "fork in the road". In this case, part of the current will pass through one element, and part, through another one.
What is the meaning of a convection current?
An electrical current produced by the movement of charged particles or bodys through space ie. not electrons flowing through a wire - it has no voltage and does not satisfy ohms law.
What will happen if you pass dc current through a single coil?
If dc current is passed through a single coil, it is going to remain constant.
How is light produced from the Sun?
Think of the sun as an H-bomb that keeps going and going and going and going and going. Eventually, it'll use up all the hydrogen in it, and it'll stop; but not while you and I are still around.
What is the voltage drop of a 1k ohm resistor?
It depends on the current going through it. Ohm's law: Voltage equals current times resistance.
What will be the current reading on the ammeter?
You measure the amount of volts(I) going through whatever you attached it to
How are musical tones produced?
Musical tones are produced by the sound waves going through instruments and depending on the size shape and holes the are in the instrument. they vibrate off of the sounds.
How much does a shuttle cost from Paris to London?
If you are trying to get from Paris to London, depending on who you're going through, it should cost around $18. If you are going through a tour company, it's going to cost you around $75.
Is eminem fat?
Not right now. There were rumors going around that he was, but his current weight is 175 pounds.
Who discovered that electric current going through a wire can create a magnetic field?
Hans Christian Ørsted
What is the best instrument to use to determine if current is going through a wire in an automobile?
12 volt test light
What is described as an automatic switch that acts as a safeguard in an electric current?
A fuse is a piece of metal or a resistor that fails when the electrical current going through it exceeds a safe level
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.
