I noticed that you asked a CST Testing Practice Fifth Grade Science question. It would be D, because it has the most coils. The more coils, the greater the magnetic field.

Where there is magnitude of the magnetic field around a permanent magnet greatest?
I am not sure but magnitude of magnetic field around its poles is greatest.
What are the types of magnets?
Ferro-magnets, permanent magnets, temporary magnets, and electromagnets. Ferro-magnets are magnets that are magnetic at a higher temperature than room temperature. do not quote me on that. permanent magnets are magnets that are always magnets, they are the kinds you use a lot. Temporary magnets are things that are magnetic in an extrenal magnetic field. Last but not least, electromagnets. Electromagnets are coils of wire around a cobalt, nickel, or iron. When ou run electricity through the wire, the core and wire become magnetic.
What does an electromagnet need to generate a magnetic field?
Magnets can be divided into electromagnets and permanent magnets. An electromagnet consists of a iron core surrounded by a coil of wire. When an electric current passes through the wire coil, it will generate a magnetic field, which will be stronger because of the iron core. Iron is not the only material for the core, any ferromagnetic material may be used, some of which are ceramics. If there is no current in the coil, there will be no magnetic field. Have you seen pictures of crane - mounted electromagnets used in scrap yards?
List the factors on which the strength of the magnetic field of an electromagnet depends?
The strength of an electromagnets magnetic field depends on:The type of core metalThe ability of the wire to carry current (its material and thickness)The number of turns of the wiring around the coreThe voltage/current of the electricity going through the wire.
What is the neutral point of the magnetic field?
In a combined magnetic field, a neutral point is a place where the magnetic field is zero
What is the different electromagnets and permanent magnet?
Electromagnets are non permanent magnets. They got magnetic field because of applied electric field. They lost their magnetic field which was around that, when the applied electric field is stopped. permanent magnets have magnetic property always with it. Permanent magnetic property loses when we heat the material. It cannot be regained once again. But electromagnets are capable of regaining its magnetic properties.
What happens if an electromagnets ecectricity is turned off?
The magnetic field dies.
What is affected by electromagnets?
Other magnets, as well as magnetic substances such as iron, in which magnetism is induced by the external magnetic field.
Compass magnets can only be deflected by electromagnets such as Earth's magnetic field?
This is FALSE. TWICE!The Earths magnetic Field is not Electromagnetic.A compass can be deflected by any Magnet.
What 1 major difference between bar magnets and electroagets.?
Electromagnets only have a magnetic field when electrical current if flowing through them. When the power if off, so is the magnetic field. A bar magnet ALWAYS has a magnetic field.
Can an electromagnets strength be changed?
The more electricity the more powerful the magnetic field. Increase the voltage, which for the given resistance of the coil, will also increase the current and the magnetic field.
Where there is magnitude of the magnetic field around a permanent magnet greatest?
I am not sure but magnitude of magnetic field around its poles is greatest.
Where is the magnetic force the greatest on a magnet?
The magnetic force of a magnet is strongest at its poles. This is because the field lines of the magnetic field are most concentrated at the poles where they enter and leave the magnet. At the poles the magnetic field is strongest and the force is the greatest. The north pole is where the magnetic field lines enter the magnet. The south pole is where the magnetic field lines leave the magnet. The magnetic field lines are most concentrated at the poles. The magnetic force is greatest at the poles.
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.
How is an electromagnet different from a regular bar 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.
What are two primary differences between an electromagnets magnetic field and earths magnetic field?
First one is artificial where as the latter is natural We could increase or decrease the strength of magnetic field but we cannot vary earth's Intense field could be produced but earth's field is feeble in comparison with artificial
What are some ways to increase the magnetic field strength?
Increase the size of the magnet. Increase the current passing through the wires (electromagnets) Increase the number of coils of the wire (electromagnets)
