Yes, if you place your thumb in the flow direction, the magnetic direction around the wire will be ccw.

Why is the magnetic field strngth inside a current carrying loop of wire greater than a strraight section?
A looped wire would have a stronger magnetic field because a looped wire is closer to the magnet all the way aroud.
How can electric currents and magnets exert force on each other?
Electric currents and magnetic fields are by nature and by definition related to each other. In general, a magnetic field is created by the rotation of charge. If you imagine an electron following a circular path, a magnetic field would be created in the direction perpendicular to the plane of the circle.On the other hand, electric current is defined as the flow of charge. So, an electron flowing along a wire results in current flow. This also means that the electron following a circular path (as above) creates an electric current along that same path.If a circular flow of current results in a magnetic field perpendicular to the circle, what happens for current flow along a straight wire? Basically, we see a magnetic field which bends around the wire. Imagine exactly the reverse as before, with the magnetic field circling around the direction of current flow.This basic relationship between electric current and magnetic fields results in some interesting interactions:1. Many electromagnets work by the following principle: A coil of wire is made so that when voltage is applied the current will follow a circular path. As discussed above this circular movement of charge results in a magnetic field. In this case, you can imagine the direction of the magnetic field as the line through the center of the wire coil.2. The Hall Effect: When current is applied across a conductive slab and a magnetic field is applied perpendicular to current flow, a voltage is generated in the third perpendicular direction. This occurs due to the interaction of the magnetic field generated by the flow of current and the applied magnetic field.
What condition will sinusoidal voltage be generated in a coil of wire that rotates in a magnetic field?
a generator or alternator,if the magnetic is permanent the current produced from the coil will be alternating current ac.
Is there a magnet in an electromagnet?
An electromagnet is a type of magnet in which the magnetic field is produced by the flow of electric current. The magnetic field disappears when the current ceases. Take a look at this Wikipedia page for more information: http://en.wikipedia.org/wiki/Electromagnet
What repels magnets and what attracts magnets?
A. An aluminum wire carrying current B. An electromagnet C. An iron horseshoeA. A copper wire carrying current B. An iron horseshoe D. A steel paper clip
How will you describe the magnetic field around a straight current-carrying wire?
the magnetic field gets stronger with increasing distance from the wire
What is the shape of magnetic lines force in case of a straight current carrying conductor?
circular
Suppose that you're facing a straight current-carrying conductor and the current is flowing toward you. The lines of magnetic force at any point in the magnetic field will act in?
A clockwise direction
How would you describe the magnetic field produced by a current in a straight wire?
Yes. It depends on its resistivity
What is the cause of a magnetic field about a current-carrying wire?
The cause is the current.
What statements describes the result of reversing the current in a current-carrying in a magnetic field?
When the current is reverted, the magnetic field will also be reverted.
When is the force experienced by current carrying conductor placed in a magnetic field strongest?
The force experienced by a current carrying conductor placed in a magnetic field is strongest when that conductor is placed perpendicularly to the magnetic field.
Why does the current carrying conductor experiences a force when it is placed in magnetic field state Fleming's left hand rule?
The force on current carrying conductor kept in a magnetic field is given by the expression F = B I L sin@ So the force becomes zero when the current carrying conductor is kept parallel to the magnetic field direction and becomes maximum when the current direction is normal to the magnetic field direction. Ok now why does a force exist on the current carrying conductor? As current flows through a conductor magnetic lines are formed aroung the conductor. This magnetic field gets interaction with the external field and so a force comes into the scene.
In a current carrying conductor what exist around it?
a magnetic field
Does coil of wire carrying a current have a magnetic field?
yes
Will a copper wire not carrying a current be attracted to a magnet?
No, a copper wire that is not carrying a current will not be attracted to a magnet. Copper is not a magnetic material, so it does not interact with magnetic fields in the same way that magnetic materials like iron or nickel do.
What happens when you reverse the current in a current-carrying magnetic field?
The polarity of the electromagnet reverses.
