What are the similarities and differences between a solenoid and a bar magnet?
DIFFERENCE: a bar magnet is a permanent magnet where as solenoid is a electromagnet so it acts as a magnet only when electricity is passed through it. SIMILARITIES: they both act as magnets and both have a similar magnetic field.
What happens to a bar magnet when it is cut in half?
The bar magnet becomes two smaller barn magnets.
What are 5 types of artificial magnets and state their uses?
Bar magnet, ball ended magnet, cylindrical magnet,horse shoe magnet, round magnet
What is the magnetic field of an electromagnet similar to?
a bar magnet...
Why there is an induced current in a coil when the bar magnet is thurst into the coil?
This is called ELECTROMAGNETIC INDUCTION. The electrons have a magnetic field; the magnetic fields of electron and bar magnet interact. Both the bar magnet and the electrons are "pushed". The electrons are lighter; they move more easily. Moving electrons are called a current.
What does a magnet field in a solenoid resemble?
a 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 is earths magnetic field similar to that of a bar magnet?
electric current in a solenoid coil
The use of bar magnet in chemistry?
The magnet bar is used for stirring solutions.
What if a current passes through solenoid If yes then what happens in the whole process?
Yes. DC can pass through. As it passes through then solenoid would act as if 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.
Where are the two types of electromagnet and a bar magnet commonly used?
I'm not sure where a bar magnet is used, but an electromagnet is used in junkyards, and in some laboratories.
What is a bar magnet used for in chemistry?

How do you magnetize steel bar?
a steel bar is a magnetically susceptable material. if you apply a magnetic field through the steel bar, such as applying a DC current through a solenoid winded around it, it will become magnetized. Just rubbing a magnet against the steel bar will help align all the magnetic dipoles in a general direction for it to be considered a magnet.
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
