Do field lines around a current wire look different from those around a bar magnet?

Yes. The field lines of a bar magnet emerge from one end, curve around, and stop at the other end.
The field lines around a current-carrying wire are circles, with the wire passing through their centers.

What is produced around a wire that has a current?
Magnetic field.
Region around a magnet in which magnetic force can act?
Magnetic freild
How does electromagnetic induction produce induced current?
Before you can understand how electrical energy is supplied by your electric company, you need to know how it is produced. A magnet and a conductor, such as a wire, can be used to induce a current in the conductor. The key is motion. An electric current is induced in a conductor when the conductor moves through a magnetic field. Generating an electric current from the motion of a conductor through a magnetic field is called electromagnetic induction. Current that is generated in this way is called induced current. To induce a current in a conductor, either the conductor can move through the magnetic field or the magnet itself can move.
How are electromagnetic fields different from a magnetic field?
Electromagnetic fields can be varying in intensity. A magnet is static.
Is there a magnetic field around current carrying conductors?
yes.magnetic field present around the conductor.current and magnetic fields are inter related..with current we can produce magnetic field and vice versa
How can a magnet field be produced around a wire?
By passing a current threw it.
How does an electric current make a magnet?
the electric current is generated by the electric field. thus by the left hand rule when current is passed through a conductor a magnetic field is generated around it so that it is a similar act of a magnet. thus it seems to be a magnet.
How is an electromagnet different from a refrigerator magnet?
A refrigerator magnet is magnetic because it is a "permanent" magnet. An electromagnet is a magnetic field caused by a current flowing through a wire.
What is the A magnet that has coils of ccurrent-carrying wire around an iron core?
The current produces the magnetic field; such a magnet is called an electromagnet.
Where is the field around a magnet strongest?
Where is the magnetic field around a magnet strongest? Answer: A magnetic field is strongest around the poles. Your welcome! :)
What is the field around a magnet?
A magnetic field. where attraction and repulsion takes place around the magnet.
What are the three characteristics of a magnet field by a current?
.
What is a shape of a magnet field?
Depends on the shape of the magnet, but in general, the field is spheroid around the pole of the magnet.
How is an electromagnet different from a regular a magnet?
An magnet is a material or object that creates a magnetic field. Bar magnets constantly create their magnetic field, while electromagnets are coils that only produce a magnetic field when an electric current passes through it.
In which case will electric current be induced in a coil of wire?
The coil must experience a changing magnetic field in order to have a current induced. You can rotate the coil between the poles of a magnet, or rotate the magnet around the coil.
How can an electric current cause an iron nail to become a temporary magnet?
By making the magnetic field around it a negative charge
How can an electrical current cause an iron nail to become temporary magnet?
By making the magnetic field around it a negative charge
