What is the purpose of the soft iron core used in making electromagnet?
The purpose is to enhance the magnetic field - to make it stronger - compared to just using air.
How do you make a sentence for magnetic field?
The magnetic field of the Earth protects us from cosmic radiation.
Can a silver coil make a magnetic field?
It is the flow of ELECTRICITY that makes the field in a coil. Therefore a coil of any conductor will make a field. Silver is a conductor.
Why does more coils make an electromagnet stronger?
The illustration on the HowStuffWorks website is probably the easiest to understand. As you add coils to the electromagnet you have more and more magnetic field traveling in a certain vector (depending on which way current is flowing). It's much like a lot of physics...as you add horses to a plow the force is increased. As you add coils to an electromagnet the magnetic field increases. As I said, check out this link for better understanding. http://science.howstuffworks.com/electromagnet4.htm\ A wire with an electric current passing through it, generates a magnetic field around it, this is a simple electromagnet. The strength of magnetic field generated is proportional to the amount of current. if we were to increase the number of coils the strength of the magnetic field would increase, also increasing the strength of the magnet
How do you produce a uniform magnetic field?
To make a long story short I wanna mention the name of several methods to make uniform dc magnetic fields: Using the space inside a solenoid Using the Helmholtz coil Using the Maxwell coil as all of these configurations take benefits of the phenomena in which current produces a magnetic field, the amplitude of the magnetic field would be easily controlled by control upon the current passes the loops of windings.
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.
What effect does increasing the number of coils have on an electromagnet?
Adding more coils will make the magnetic field stronger. Magnetic field increases.
In an electromagnet the magnetic force increase as increase?
Adding more coils will make the magnetic field stronger. Magnetic field increases.
Are magnetic forces stronger when heated or cool down?
Magnetic fields are stronger when cooled down. This is because the atoms that make up the magnetic material aren't moving as fast as a heated magnet's atoms. This means that the magnetic domains are less likely to move out of place and mess up the magnetic field.
What makes electromagnetism stronger?
electricity is used to make the magnetic pull stronger.
In an electromagnet how do you make a stronger magnetic field with a single wire?
according to ampere's circuital law,magnetic field is directly proportional to the current flowing through the conductor.thus magnetic field can be increased by increasing the current through the conductor,provided the conductor or wire is capable of carrying high currents i.e. it should be of good conductance.
What is the purpose of the soft iron core used in making electromagnet?
The purpose is to enhance the magnetic field - to make it stronger - compared to just using air.
How do you make a sentence for magnetic field?
The magnetic field of the Earth protects us from cosmic radiation.
What are three things you need to make an electromagnetic?
Three things you need to make an electromagnetic are a magnetic field, an electric current, and a conductor or coil of wire. When an electric current flows through the conductor, a magnetic field is created around it, resulting in an electromagnetic effect.
How does an electric coil works?
when u give supply to a coil then a current will be passed through it .naturally a magnetic field is produced around the c.c.c(current carrying conductor). when u make more turns in the same direction the whole magnetic field will be stronger than that of a wire has. andby lenz's law there will be an opposition to the changing current in a coil due to the change in magnetic field produced
How do you make a Magnetic forces?
by bring two magnets near we can make magnetic field for some distance.
What are sources make up the earths magnetic field?
The earth's magnetic field is caused by convection currents in our core. The core is made out of iron, which is a magnetic metal.
