What will happen if you place a magnetic compass in an electric curcuit?
The compass will align itself with the magnetic field generated by the current flow through the wires.
What can happen to sound energy travelling through the air when it meets a new substance?
the substance can change the sound energy and make you here something else.......
What energy convertions happen in an electric motor?
Electrical into magnetic, and then magnetic into mechanical.
Why the the reading on the newton meter increases when a current passes through the coil?
because it becomes more magnetic therfore it the pull on the coil will increase
Why does a magnet work?
Basically, all electrons are naturally little magnets. They produce an electromagnetic field. We won't worry too much about how and why this happens, just take it as given that it does happen. This property of electrons is, for historical reasons, called "spin".In most materials, the electrons get "paired up": One having a "spin up" will get paired with one having a "spin down", so their magnetic fields cancel out within a single atom or molecule.However, some materials are ferromagnetic. They have lots of unpaired electrons, so their spins don't cancel out on an atomic level. They may still cancel out with the atom next to them... this is why most iron bars (iron is a ferromagnetic material, and the word "ferromagnetic" actually comes from the Latin word for iron, ferrum) are not magnets: each tiny iron atom has its individual magnetic field pointing in a different direction, so that for every one that's pointing west there's another one pointed east and for every up there's a down and for every south there's a north and so on.If you can get all the atoms to "line up" with their tiny magnetic fields all pointing the same direction, you get a permanent magnet, like the little toy magnets you can buy.You can also temporarily make them line up using electricity. An electric current in a coil of wire makes a magnetic field, but if you put a ferromagnetic substance in the center of the coil, it intensifies the field, and you get an electromagnet.Even if a ferromagnetic material isn't a magnet itself, it's still attracted by other magnets. This is why you can stick a magnet on your (steel) refrigerator, or use one to pick up (iron) nails.
What happen if the iron core is replaced by gold in the case of transformer?
You will have a very expensive but worthless transformer. Gold is not a ferromagnetic material, so it will not contain the magnetic flux needed to link the separate windings.
What will happen if you place a magnetic compass in an electric curcuit?
The compass will align itself with the magnetic field generated by the current flow through the wires.
What happen to magnetic compass if the current is changed?
If an electric current flows through a wire, it will create a magnetic field. ... a ship or an airplane, it can damage or otherwise change the ship's magnetic compass.
What has to happen around a coil of wire to generate an induced current?
pass a magnetic field through the coil of wire.
When did Magnetic Soccer happen?
Magnetic Soccer happened in 1992.
What will happen to the world if there is no magnetic induction?
if there is no magnetic induction there will be no electricity
What can happen to sound energy travelling through the air when it meets a new substance?
the substance can change the sound energy and make you here something else.......
What would happen if the direction of the current through a hall probe is reversed?
The idea is that the magnetic field of the device reacts with the external magnetic field. If the current is reversed, the magnetic field would also be reversed, and the reading would be the opposite.
When did Super Magnetic Neo happen?
Super Magnetic Neo happened in 2000.
What energy convertions happen in an electric motor?
Electrical into magnetic, and then magnetic into mechanical.
If you transmit a certain amplitude freqency wave through a high voltage or magnetic field then what will happen to the transmitted wave?
Distortion and static, as radio waves (assuming that's what you are talking about) are electro-magnetic by definition.
What happen to the heat energy as a substance solifies?
what happen to the heat energy as a substance solidifies
