What does the Earths magnetic field resemble?
That of bar magnet..
What shape of a permanent magnet corresponds to the magnetic field formed by a solenoid?
The magnetic field produced by electric current in a solenoid coil is similar to that of a bar magnet.
How does a solenoid act as a magnet?
When current is passed through a solenoid coil, magnetic field produced due to each turn of solenoid coil is in the same direction. As a result the resultant magnetic field is very strong and uniform. The field lines inside the solenoid are in the form of parallel straight lines along the axis of solenoid. Thus, the solenoid behaves like a bar magnet.
Which factors affect the magnetic strength of a solenoid which is carrying an electric current?
Factors affecting the magnetic field strength of a solenoid are: - length of the solenoid - diameter of the solenoid - current through the coil around the solenoid - number of turns of the coil of current around the solenoid, usually turns of wire - material in the core
Pattern of field lines due to solenoid carrying electric current?
From my text book: You'll see that inside a solenoid the magnetic field is etremely strong, this can be used to magnetise objects. The field around it is exactly the same as the field around a bar magnet. Concentrated inside the solenoid and gradually getting more spaced out the further away
What does a magnet field in a solenoid resemble?
a bar magnet

That of bar magnet..
What shape of a permanent magnet corresponds to the magnetic field formed by a solenoid?
The magnetic field produced by electric current in a solenoid coil is similar to that of a bar magnet.
Will increasing the number of loops in a solenoid cause the strength of its magnetic field to decrease?
No; increasing the number of loops in a solenoid will cause the strength of its magnetic field to increase.
What is the main difference between a relay and a solenoid?
A relay is a switch - a solenoid produces a magnetic field.
The magnetic field of a solenoid can be increased by?
A: adding more loops
Can a planet have a quadrupole magnetic field?
Yes - several planets have magnetic fields that do not even vaguely resemble Earth's current field.
The magnetic field around a solenoid has a configuration similar to the field of a long straight wire?
no
How does a solenoid act as a magnet?

Thus, the solenoid behaves like a bar magnet.
What are some examples of a solenoid?
elecrical current creates a magnetic field
What effect does increasing the current have on solenoid?
it will produce a stronger magnetic field.
How is solenoid a magnet?
A Solenoid is an electro-magnet. It has coils of wire, usually copper. When an electric field is applied to the coils of wire, an magnetic field is generated. This magnetic field attracts a steel or iron segment on the switch and activates the switch.
