What types of materials behave like iron when place in to magnetic field?

Elements that are paramagnetic can act like iron when placed in a magnetic field. This is because of the presence of unpaired electrons in their valence shell. For example, liquid oxygen can have some magnetic properties (attracted to the magnet) when poured between the poles of a magnet.

What is electromagnetic induction?
Electromagnetic Induction mainly deals with the ways that energy is shifted about between Electric and Magnetic fields in various circumstances. Here are some major examples:1. A moving Electric Current Induces a Magnetic field: Electromagnets.2. A moving conductor in a magnetic field Induces an Electric Current: The Dynamo or Electric generator.3. An Electrified Conductor in a Magnetic field Induces motion in the Conductor: The Electric Motor.Related Information:Albert Einstein's considerations of inductance, an Electrified length of conductor moving through a Magnetic Field in an empty volume of space, led him to his theory of Special Relativity.
How is the left-hand rule related to current and magnetic field?
It is related to the flow of electrons in a conductor through aseparate magnetic field. If you point your index finger straight place your thumb up and place your middle finger at a 90 degree angle to the other two (unless you are really double jointed there is only one way to do it.). The direction of current and your wire is the middle finger the direction of magnetic plane pointing north is your index finger and the direction of force is your thumb. There is also the right hand rule. If you look at your right hand with your thumb up and fingers curved, If you held a piece of wire in your hand with the current traveling along the direction of your thumb the magnetic field would rotate in the direction of your fingers.
Why are you able to perceive certain electromagnetic fields?
we make use of the observation that a charge (whether magnetic or electric, hence electromagnetic) in a field experiences force. For example, a wire carrying a current builds up a magnetic field around it, and when we place something with a magnetic charge near it (like a compass needle) it pushes the needle to try to line it up with the field (it's definitely not that simple, but it works unless you start doing the calculus and Fourier Transforms). Another neat trick; if we bring a second wire close to the first wire carrying the current, the field pushes on the electrons in the second wire and that tries to make a current in the second wire. This trick works on almost all electromagnetic fields, whether made by current flowing or by something else.
Why induction motor is called asynchronous motor?
as we know that a rotating magnetic field is created by the satator current,and so in the rotor there is induced current and there by the rotor developes a unidirectional torque. so since the rotor runs with a speed other than the synchronous speed of rotating magnetic field produced by stator current so it is called as asynchronous motor.. asynchronous -means not moving with synchronous speed --------------------mrityunjay (kiit university . b.tech 2nd year student)
What are the advantages of Permanent magnet over Electromagnet?
Unlike a permanent magnet, an electromagnet can be turned on and off. One useful advantage of this: Place a metal bar inside the electromagnet, apply current through the electromagnet in one direction, and the magnetic field would move that bar one way -- reverse the current reverses the magnetic field and the bar would move the opposite way. You could use that effect and make an electronically controlled lock for a door.
What is the neutral point of the magnetic field?
In a combined magnetic field, a neutral point is a place where the magnetic field is zero
What is the neutral point of the magnet?
In a combined magnetic field, a neutral point is a place where the magnetic field is zero
What is uniform and non uniform magnetic field?
Uniform magnetic field depends on the position of its surrounding. A non uniform magnetic field changes its position from one place to another.
How does a compass needle respond when a compass is Place with in a magnetic field?
If a magnetic compass needle is placed in a magnetic Field , its needle deflects and points in the north and south directions

How yo find the magnetic field of earth at a particular place?
Using a compass is the easiest way. The needle is going to point to the Magnetic North Pole. That means that the compass needle is ALIGNED with the Magnetic Field Lines of the Earth's magnetic field at your current position.
What is the field around a magnet?
A magnetic field. where attraction and repulsion takes place around the magnet.
Where do magnets come form?
A magnetic field is generated by a moving electric charge. The fundamental place where such a charge lies is on the electron. So when an electron moves (including just spinning in place), it generates a magnetic field. A common substance will have equal numbers of clockwise and anti-clockwise spinning electrons, and there will be no net spin, and therefore no net magnetic effect. In some materials, a group of magnetic domains will aggregate, thus becoming a 'permanent magnet'. Some of these are natural materials. And, when an electric current (a flow of electrons) moves down a conductor, it will generate a magnetic field.
How do you provent from a magnet?
* Magnetic field weakens with the square of distance -- place the magnet as far away as possible. * Magnetic field is shielded with metal -- wrap the magnet in metal films, the best being ferromagnetic materials, such as iron, cobalt, etc. * use a de-magnetizer frequently on the objects that you don't want to be magnetized. =============================
What do we call a place where there is no magnetic field?
I don't believe there is a special name for that, so you can just use a term similar to what you wrote in the question, for example, "a region with no magnetic field".
Why splitting of spectral lines take place in magnetic field?

A charged particle moving with a constant velocity enters a magnetic field?
when a charged particle is moving with some velocity it produces some magnetic field. If we place that charged particle in presence of external magnetic field it gets affected by that external field.
