i have no idea yes
Certain materials are magnetic because their atoms have unpaired electrons that create a magnetic field. This magnetic field allows the material to attract or repel other magnetic materials.
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.
As distance increases from a magnetic source, the strength of the magnetic field decreases. This is because the magnetic field follows an inverse square law, meaning that the farther away you are from the source, the weaker the magnetic field will be.
Magnetic materials are magnetized by exposing them to a magnetic field, such as from a magnet or an electromagnet. This causes the magnetic domains within the material to align, creating a net magnetic field. The material retains this magnetic field even after the external field is removed.
The region where magnetic force can be felt is called a **magnetic field**. This field surrounds magnetic materials and electric currents and exerts a force on other nearby magnets, magnetic materials, and moving electric charges. The strength and direction of the magnetic field can vary, but it extends outward from the source of the magnetic force.

a magnetic field can lift some metals not all.
Many materials which are capable of being effected by a magnetic field will retain some of those properties once its no longer in direct contact with the field. One example is iron. It can become magnetized by being introduced to a magnetic field and then continue to remain magnetic once the source field is removed.
Magnetic materials are materials that can be magnetized and can create a magnetic field, such as iron and nickel. Non-magnetic materials do not respond to magnetic fields and cannot be magnetized, such as wood and plastic.
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.
A strong magnetic field has a higher magnetic flux density than a weak magnetic field. This means that a strong magnetic field exerts a greater force on nearby magnetic materials compared to a weak magnetic field. Additionally, strong magnetic fields are more effective for magnetizing materials or creating magnetic induction.
No. The source of earth's magnetic field is the molten inner core. The moon due to its proximity of course influences our magnetic field but it is to be considered a "weak effect".
