A magnetic field is invisible, but its presence can be detected by placing a compass near a magnet. The magnetic field lines around a magnet are depicted as flowing from one pole to the other, forming a looped shape. The strength of the magnetic field is strongest near the poles of the magnet and weakest at its center.

What does a magnetic field look like around a current carrying a wire?
Around a current-carrying wire, the magnetic field forms concentric circles perpendicular to the wire. The strength of the magnetic field decreases as you move away from the wire. The magnetic field direction follows the right-hand rule where your thumb points in the direction of the current and your fingers show the direction of the magnetic field.
What is residual magnetic field?
A residual magnetic field is the magnetic field that remains in a material after an external magnetic field is removed. This phenomenon occurs in materials with magnetic properties, such as ferromagnetic materials like iron. Residual magnetic fields are used in various applications, such as in magnetic storage devices like hard drives.
Does Eris have a magnetic field?
No, Eris does not have a magnetic field. It is a dwarf planet located in the outer solar system and does not exhibit any magnetic field like some other planets do.
Why is there a magnetic field even when there is no current?
A magnetic field can exist without current due to the intrinsic magnetic properties of particles like electrons. In atoms and materials, the alignment of these particles' spins can create a magnetic field. This is known as magnetism and is responsible for phenomena like the Earth's magnetic field.
Does everything possess a magnetic field?
Not everything possesses a magnetic field. Materials that have magnetic properties, such as iron, nickel, and cobalt, can generate a magnetic field. Other materials, like wood or plastic, do not have magnetic fields.
What does a magnetic field for a toroid look like?
A magnetic field for a toroid is typically concentrated within the coil, circling around the winding. Inside the toroid, the magnetic field lines are close together and form closed loops. Outside the toroid, the magnetic field is very weak and essentially negligible.

Is it true or false that an electric charge creates a magnetic field?
Opposites attract, like charges repel each other.

What do magnetic field lines look like when two magnets attract each other?
When two magnets attract each other, the magnetic field lines curve from one magnet to the other in a continuous loop, showing the path of the magnetic force between them.
Does the moon have a stronger magnetic field than the earth?
No, the moon does not have a global magnetic field like Earth. Some localized magnetic fields have been detected on the moon's surface, but they are much weaker than Earth's magnetic field.
The area around an object that is affected by the magnetism of that object is the?
A Magnetic Force
How does the spinning proton magnetic field contribute to the behavior of particles in a magnetic field?
The spinning proton magnetic field influences the behavior of particles in a magnetic field by aligning with or against the external magnetic field. This alignment affects the energy levels of the particles, leading to phenomena like nuclear magnetic resonance and the Zeeman effect.
What does a speed sensor look like?
thick splines on a steel shaft on the hub spindle rotating past a magnetic field.
