Iron core (usually soft iron core) is a highly ferromagnetic material. Ferromagnetic materials allows (and attracts) the magnetic field lines to pass through it.
When such a material is used in the electromagnet, the magnetic field lines passing through it increases, thereby, the strength of the electromagnet increases.

So my friend, I hope you are satisfied with the answer.

# How can you increase the strength of a electromagnet?

Answer you can increase the strength of an electromagnet by: 1) Increasing the current flow 2) Increasing the number of coils 3) Passing an 'iron core' through the coil of the

# How can you increase the strength of an electromagnet?

You can increase the strength of an electromagnet by either increasing the number of turns, and/or by increasing the current, and/or by increasing the ferromagnetic density (p

# How can the strength of an electromagnet be increased?

There are two basic ways: More turns More current

# Why does the strength of the electromagnet increase from the coils?

Because increasing the number of coils also increases the amount of wire on its core.

# The strength of an electromagnet cannot be increased by?

-- gluing heavy weights to it -- painting it red -- hanging it on the wall -- shouting at it -- soaking it in brine -- making it do exercises -- heating it -- freezing it -- t

# Why is iron used as the core of an electromagnet?

because exhibits maximum flux density requires small magnetising field exhibits low hysteresis loop

# How does the strength of a wooden core electromagnet compare with that of the iron core electromagnet?

Electromagnets consist of wire coiled around a core. The core can be anything from air to a nail or even a pencil. Since electrons flow freely through a conductive core (like

# What increases the strength of a copper electromagnet?

Wrapping the copper wire around an iron nail, increasing the current. Increase the power going through the wire or have more wire wrapped around the metal object. So in the ca

# What will increase the strength of a copper electromagnet?

One way to increase the strength of a copper electromagnet is byadding another coil. Another way is by wrapping the copper coilaround a nail made of iron. Adding more loops to

# Increase the strength of a copper electromagnet?

There are a couple of ways to increase the strength of a copperelectromagnet. You could increase the current going through thewire or wrap more wire around it which increases

# How the strength of an electromagnet can be increased?

By increasing the number of coils in the wire, increasing thecurrent or by adding a core of soft iron inside the solenoid.

# How can you increase the strength of a horseshoe electromagnet?

I suppose this can be done with some wiring around it and then add voltage with heavy current to the wiring. If the electricityflow is correct, it will magnify the magnetic f

# Why does the soft iron core increases the strength of magnetic field?

The soft iron core acts as a medium through which magnetic fields can flow ANALOGY: Just as sound travels best in dense solids, magnetic fields travel best in [soft] iron W

# Why do electromagnets often have iron cores in them?

The main advantage of an electromagnet is it can be turned on and off. Iron is a soft magnetic material an therefore looses its magnetism very quickly, if you use a metal like

# Why do most electromagnets have an iron core?

Most electromagnets have an iron core as it increases the strength of the electromagnet. :) Hope I helped and was right :)

# What are methods of increasing electromagnetic strength?

I'll assume you mean "the strength of an electromagnet". An electromagnet gets stronger when you ... . - increase the current (amps) through the wire - increase the num

# Why is an iron core needed in an electromagnet?

An iron core is needed in an electromagnet because it serves toincrease the magnetic field created.
