No. Any current produces a magnetic field. Look at Maxwell's equations.

Do batteries have the ability to generate a flow of electrons?
yes Batteries only produce direct currents
What is the use of capacitor in three phase induction motor?
Only Single phase induction motors need capacitor to star it, because of single phase. With the help of capacitor in the starting winding circuit it is easy to create rotating magnetic field inside motor which is responsible for running of motor.
What best describes magnetic field lines?
Magnetic fields are produced because of moving electric charges, and visualizing the very complex mathematical relationships that fall under the magnetic field might become much easier if magnetic field lines were used. A higher density of field lines means a stronger magnetic field. Keep in mind that those lines do not actually exist; they are drawn only to visualize the strength of the magnetic field.
Are the magnetic field vector- or scalar fields?
Both, E=Es + Ev = cB therefore, B= Es/c + Ev/c = Bs + Bv. The electric and magnetic fields are quaternion fields consisting of a scalar field and a vector field. Contemporary Physics has not realized this yet. Correct Relativity Theory is a manifestation of quaternion fields, consisting of a scalar field and three vector fields. This shows up in the Energy Momentum four vector, E= Es +cmV. Actually the Lorentz Force is both scalar and vector: F=qvB = - qv.B + qvxB it makes no sense consider only qvxB and to ignore qv.B.
Can a magnet delete everything on a computer by just putting it on the outside?
No. A magnet only interfers with magnetic fields ... lots of old IBMs used magnetic memory cards and that's where the stories started. It might erase a floppy disk, but an electro-magnet does the job much better than a perminant magnet.
Does electricity always produce a magnetic force?
Magnetism, an aspect of electromagnetism, one of the fundamental forces of nature. Objects such as a bar magnet can influence other magnetic materials, without physically connecting them, because magnetic objects produce a magnetic field. Magnetic fields are usually represented by magnetic flux lines. Magnetic fields influence magnetic materials and also influence charged particles that move through the magnetic field.
Can an electric current exert a force on a magnet?
In a conductor - only if the field is moving, thus changing.
What fields gravational magnetic or electric can only exist in one direction?
gravitational
Can magnet attract aluminum?
aluminum is not magnetic. the tree metals that ARE magnetic are : Nickel Iron Cobalt Kinda, only if eddy currents are induced with movement
Can electric currents produce sound?
the only sound is from the power source
Can a magnetic field pass through steel?
No, magnetic fields can only pass through non-magnetic objects (e.g cloth)
Does moving electricity cause a magnetic field?
Magnetic fields are only caused by moving electrons. In the case of a current flow, this is the common experience.For a permanent magnet, this effect is caused by the alignment of a number of spinning electrons into a magnetic domain. All their spins pointing the one direction.The magnetic fields and loops on the Sun are caused by currents flowing in the Sun's body. At many thousands of degrees, it is impossible for a magnetic material to exist. This is known as the Curie Temperature - another discovery by Marie Curie - and is the temperature above which a magnetic may be maintained in a material. In essence, the thermal motions of the molecules are too vigorous to permit the creation of aligned magnetic domains.
What creates a planet's magnetic field?
The dynamo. For terrestrial planets, the dynamo is a molten core of nickel-iron. Mercury and Earth have fairly strong dynamos and therefore fairly strong magnetic fields. Venus and Mars do not, and have only weak magnetic fields.
Do clothes dryers have magnets in them?
A clothes dryer usually has only one part that has any notable electromagnetic characteristics. (The electronic control circuit is not magnetic beyond the fact that it has wires that carry currents.) The part that employs magnetic fields in its operation is the electric motor. Most electric motors do not have permanent magnets in them but have field and stator coils that induce the electromagnetic fields. Only small electric motors (usually battery operated) use magnets due to space constraints.
Are there any natural magnetic minerals?
This may shock you, but all matter is magnetic just to varying degrees. So yes there is. Here are the 4 levels of magnetic property's if you will. and examples of the minerals that have them.Ferromagnetism - a strong attraction to magnetic fields. examples would be Magnetite and Pyrrhotite.Paramagnetism - a weak attraction to magnetic fields. Example would be Platinum,Diamagnetism. , Bismuth Is the only mineral that is diamagnetic, meaning it is repelled from magnetic fields.Magnetism. Only a variety of one mineral acts as a magnet, generating magnetic fields on its own. This mineral is Lodestone, the magnetic variety of Magnetite, which found in only a few deposits throughout the world. Although it is only weakly magnetic, its magnetism is definitely discernible.
Does the alluvial conglomerate rock record the magnetic field at the time the rock formed?
No. Magnetic fields are only recorded in rocks solidified from melt containing iron.
Do batteries have the ability to generate a flow of electrons?
yes Batteries only produce direct currents
