If i get your question right, you're asking if an iron bar can just repel another iron bar; saying the distance between them would become bigger without doing anything.
The answer is no. Iron bars would only repel each other if both have been given the same polarity.
In example, if you make sure both bars are positive, they will repel. If both are negatively loaded, they will repel too.
If one is positive and the other negative, however, they will attract each other.
Hope i got your question right, and this helps you...
The iron bar would become magnetized by induction through the wire coil. It would temporarily gain magnetic properties while in contact with the coil, but would lose them once removed.
The iron bar would become magnetized when inserted into a wire coil carrying an electric current. This is because the electric current induces a magnetic field in the coil, which in turn magnetizes the iron bar.
The iron would react with the oxygen in the water to make iron oxide, or rust.
Like poles repel, opposites attract. So a N pole of one bar magnet will repel the N pole of another bar magnet. And the same applies to two S poles.
tire iron or tire bar. A short one is called a b**tch bar.
To calculate the weight of an iron bar, you need to know its length. Assuming a standard density of iron, the weight of a 12mm iron bar to be one metric ton would require a length of approximately 82.5 meters. This calculation is based on the volume of the iron bar and its density.
A iron bar is a conductor

Yes, because the keepers are made up of iron, when the magnet is in contact with it they become temporary magnet. Keepers also have a useful safety function as they stop external metal being attracted to the magnet.
you have to mine iron ore then put it in a furnace and you will get an iron bar called an iron ingot.
You can differentiate between a bar of iron and a bar of copper by testing their magnetic properties - iron is attracted to magnets, while copper is not. A bar magnet will attract small iron objects, while a bar of copper will not be attracted.
This would be an Electromagnet...... If the battery is disconnected, then the iron bar will become a permanent magnet.
