All of the fundamental types of force can be mathematically described in the form of force fields. But force involves many things. If I throw a ball, I exert force on that ball which is then accelerated as a result. The force field involved is far from obvious, although it does exist. If you understand the physics deeply, you would see that in order for me to exert a force on a ball, the electrons in the atoms in my hand have to exert a force of repulsion on the electrons in the atoms of the ball. And that electromagnetic force can be described as a force field.
What else can I help you with?
What are magnets that do not require any power of force to maintain their field called?
They are called permanent magnets. These magnets retain their magnetic field without the need for any external power source or force to maintain them.
What are examples of field forces?
Gravitational force field, electric force field, magnetic force field.
Can a charged particle move through a magnetic field without experiencing any force?
No, the particle has the following forces f= qvB= - qv.B + qvxB, the first force is a scalar force when the particle is parallel to the field and teh second force is avector force when teh particle is perpendicular to the field. If the particle is not neither parallel or perpendicular to the field, both the scalar and vector forces will be experiencd.
Do not require any power of force to maintain their field?
Objects that do not require any power or force to maintain their field are considered to be in a state of equilibrium. Once an object is in equilibrium, there are no external forces acting on it and its field will remain constant until disturbed by an external force.
How can we say that gravitational force is a field force?
Gravitational force is a field force because it acts at a distance without direct contact between objects. It is a result of the curvature of spacetime caused by mass, so objects with mass interact with this curvature to produce a force without physical contact. This force can affect objects even when they are far apart.
Can a charged particle moved through a magnetic field without experiencing any force?
No, a charged particle will experience a force when moving through a magnetic field as long as it has a non-zero velocity component perpendicular to the field. This force is known as the magnetic Lorentz force.
In a field can an object apply force to another object without touching it?
unknown answer
How do you test for coercive?
the coercivity is test by drawing B-H curve.Coericivity is defined as without giving any magnitising force it will produce magnetic field intensity.
What is the force called that moves paper clips toward a magnet without the magnet touching the paper clips?
The force is called magnetism. Magnets have an invisible magnetic field that exerts a force on objects made of certain materials, such as iron, that are within the field. This force can attract or repel the objects without direct contact.
What is the differrence between a contact force and a field force?
A contact force requires physical contact between objects to exert a force, such as friction or tension in a rope. In contrast, a field force acts at a distance without direct contact, such as gravity or electromagnetic forces.
What is the relationship between the direction of the magnetic field at any point and the direction of the force acting on a particle in that field?
The direction of the magnetic field at a point determines the direction of the force acting on a charged particle moving through that field. The force is perpendicular to both the magnetic field and the velocity of the particle.
Can An electric current be produced by a changing magnetic force?
It's not the force. It's the changing magnetic field surrounding an electricalconductor, whether or not that conductor feels any force due to the field.
