What do the poles of a magnetized needle on a compass align themselves with?
(:magnetic field :)
For atoms of a magnetized substance how is the high energy state aligned with the applied magnetic field?
antiparallel to the applied field.
Why deflection of the magnetic needle placed in a coil carrying current increases as the number of turns in the coil increases?
Deflection of the magnetic needle placed in a coil carrying current increases as the number of turns in the coil increase because as the number of turns in the coil increases the strength of the magnetic field also increases.
Does a lodestone create a magnetic field?
A lodestone is magnetized and thus produces a magnetic field around it. This can be detected by the deflection of a compass needle.
What are fero magnetic substance?
Ferromagnetic substance is items that can be magnetized by the outside magnetic field. It will stay magnetic after outside field is removed.
How a magnetic field is created and how its strength is affected?
Through a current in a conductor; it is strengthened once by making a coil of the conductor and then by inserting an easily magnetized core inside the coil
Relationship between flux density and field strength?
In simple terms, if flux density increases, then field strength increases and vice versa. The flux density is equivalent to field strength times with a variable.
When the distance from a charged particle decreases the strength of the electric field does what?
As the distance from a charged particle increases the strength of its electric field DECREASES.
What will happen when the number of turns of wire and the current flowing them increases?
The strength of the magnetic field inside the coil increases.
If a soft iron core is Inserted into a solenoid will the strength of magnetic field produced by it change?
It has been found that if a soft iron rod called core is placed inside a solenoid, then the strength of the magnetic field becomes very large because the iron core is magnetized by induction The core of the electromagnet must be of soft iron because soft iron loses all of its magnetism when current in the coil is switched off or stopped
The length of a part being magnetized by passing an electric current from one end to the other affect 1 permeability 2 strength of magnetic field 3 not affect magnetic field?
Permeability
What is meant by magnetic permeability?
All materials are magnetized when placed in the magnetic field . The material magnetized by the effect of a magnetic field is called magnetic permeability.
What invisible force does the mineral lodestone have?
The mineral lodestone, also known as magnetite, is ferromagnetic, which means that it can be magnetized. Most of the magnetite found on Earth was magnetized by the Earth's magnetic field as the magnetite formed. Most naturally occurring lodestones are magnetized, but the strength of that magnetization is much less than any common magnet and can only be detected with sophisticated equipment. The invisible force is... magnetism.
What do the poles of a magnetized needle on a compass align themselves with?

For atoms of a magnetized substance how is the high energy state aligned with the applied magnetic field?
antiparallel to the applied field.
Can Mercury be magnetized is it attracted to magnets?
Mercury at normal temperature and pressure is a liquid and will not hold a magnetic field - so it cannot be magnetized.
Cans of food in your kitchen are likely magnetized Why?
The magnetic field of Earth induces the cans of food to have north and south poles, and so they are magnetized to some degree.
