repel each other
because of their magnetic field lines
Like Parallel forces are the forces that are parallel to each other and have same direction. Unlike parallel forces are the forces that are parallel but have directions opposite to each other.
The magnetic forces between the two parallel wires are attractive, as the currents in the wires flow in opposite directions, creating magnetic fields that interact with each other. This interaction results in an attraction between the wires due to the magnetic forces.
Anti-parallel
An electric field parallel to an electric dipole will exert a torque on the dipole, causing it to align with the field. An electric field anti-parallel to an electric dipole will also exert a torque on the dipole, causing it to rotate and align with the field in the opposite direction.
Examples of unlike parallel forces include lifting a box with one hand while pushing it with the other, or pulling a wagon from opposite directions with two ropes. These forces have different magnitudes and act in opposite directions along parallel lines.
parallel lines
Two (or more) lines are parallel if they are pointing in the same (or exactly opposite) directions.
The process is called bidirectional replication. In this process, DNA polymerases synthesize new strands in opposite directions on each template strand.
Antiparallel refers to a configuration where two molecules or structures run in opposite directions. In terms of DNA, antiparallel describes the orientation of the two strands running in opposite 5' to 3' directions. This allows for complementary base pairing to occur between the strands.
When forces act parallel to each other but in opposite directions, they create a state of equilibrium where the net force is zero. This means that the object will not accelerate in any direction, but rather remain at rest or move at a constant velocity.
Antiparallel has a variety of meanings depending on what the subject matter is. For example, in biochemistry, it means the orientation of adjacent molecules. In traffic, its two parallel one-way streets that have traffic travelling in opposite directions.
