it has to have iron in it
An object must have magnetic properties (such as containing iron, nickel, or cobalt) in order to be affected by a magnetic field. This property is known as ferromagnetism, which allows the object to become magnetized and interact with magnetic fields.
A charged particle must be moving in a magnetic field in order to experience a magnetic force. If the particle is stationary, it will not experience a magnetic force.
In order to do work on an object, the object must move in the direction of the force applied. If the object does not move, no work is being done on the object.
In order for an object not to move, the forces on it must be balanced. This means that the net force acting on the object is zero, resulting in no acceleration and thus no movement.
Electric charges must be in motion to produce a magnetic field. When electric charges move, they generate a magnetic field around them. The strength of the magnetic field depends on the speed and direction of the moving charges.
An object must have magnetic properties (such as containing iron, nickel, or cobalt) in order to be affected by a magnetic field. This property is known as ferromagnetism, which allows the object to become magnetized and interact with magnetic fields.
if rust is forming on a wheelbarrow, it is already magnetic. Rust is Iron Oxide, and a wheelbarrow must be made of iron if there is rust on it. Iron is always magnetic, so an iron wheelbarrow would be magnetic regardless of whether it had no rust or lots of rust on it.
A charged particle must be moving in a magnetic field in order to experience a magnetic force. If the particle is stationary, it will not experience a magnetic force.
In order to do work on an object, the object must move in the direction of the force applied. If the object does not move, no work is being done on the object.
It must be moving
The object must contain ferromagnetic materials such as iron, nickel, or cobalt to be attracted to a magnet. These materials have unpaired electrons that align with the magnetic field, leading to attraction.
A lodestone is a magnetized piece of rock. They are made of made of magnetite, a type of iron ore. For a piece of magnetite to be magnetic, it must be exposed to a magnetic field.
In order for an object not to move, the forces on it must be balanced. This means that the net force acting on the object is zero, resulting in no acceleration and thus no movement.
they must be touching
no
Velocity must be changing in order for an object to accelerate or decelerate.
According to the cell theory; for an object to be considered alive, it must be made of cells and cell products.Source- Mcdougall Littel 10th grade Biology TextbookAny object that is an organic object is considered to be alive.
