Section 1

Core Idea

Electromagnetism describes how electric and magnetic fields interact — invisible forces that attract, repel, and propagate at a distance. In physics, it's one of the four fundamental forces, governing everything from light to chemical bonds. The business analog: invisible forces — brand, culture, network effects, reputation — exert pull or push on customers, talent, and capital without direct contact. Like electromagnetic fields, these forces can attract or repel, amplify or interfere. Understanding that business operates through invisible fields of influence, not just visible transactions, is the strategic insight.
Section 2

How to See It

Brand & Culture
You're seeing Electromagnetism when a company attracts top talent and loyal customers without aggressive recruiting or marketing. The "field" — culture, brand, mission — pulls people in at a distance. Strong brands are strong fields.
Network Dynamics
You're seeing Electromagnetism when a platform's existing users create an invisible pull that attracts new users. No one is being directly recruited — the field does the work. This is the electromagnetic analog of network effects.
Section 3

How to Use It

Map the invisible fields in your business. What attracts customers without direct sales effort? What repels talent you can't see leaving? Invest in strengthening positive fields — brand, culture, reputation — and identify sources of repulsion. Like electromagnetic fields, these forces compound: a strong field attracts more, which strengthens the field further.
Decision filter
"What invisible forces are attracting or repelling people from our business? Are we investing in the field, or only in direct transactions?"
As a founder
Build your electromagnetic field early — mission, culture, brand promise. These create pull that scales without linear effort. Monitor for repulsion signals: why do candidates decline, why do customers churn silently? The invisible field is always on, even when you're not actively selling or recruiting.
Section 5

Founders & Leaders

Thomas EdisonFounder, General Electric
Edison didn't just invent the lightbulb — he built the entire electromagnetic ecosystem: generation, distribution, and consumption of electrical power. He understood that the value wasn't in any single device but in the invisible field of infrastructure that connected them all. His system thinking — power stations, wiring, meters, standards — created an electromagnetic field of utility that pulled an entire civilisation into electrification. Founders can apply this by building not just products but the infrastructure and ecosystem that makes those products essential. The product is the lightbulb; the moat is the grid.

Reinforces
Polarity
Polarity describes the positive and negative poles that create fields. Electromagnetism shows what happens when those poles interact — attraction, repulsion, and field propagation. Together they explain why businesses must understand both sides of their influence.
Reinforces
Force Multiplier
A strong electromagnetic field multiplies force — a small input creates a large effect at distance. In business, brand and culture act as force multipliers, making every marketing dollar or recruiting effort more effective when the field is strong.
Tension
Chain Reaction
Chain reactions are direct, sequential, and visible. Electromagnetic effects are indirect, simultaneous, and invisible. The tension: some business dynamics are chain reactions you can trace step by step; others are field effects that influence everything at once. Know which you're dealing with.
Section 8

One Key Quote

"Nothing is too wonderful to be true, if it be consistent with the laws of nature."
— Michael Faraday
Section 11

Summary & Further Reading

Invisible forces — brand, culture, reputation, network effects — attract and repel at a distance. Invest in strengthening your positive field rather than relying solely on direct transactions. Like electromagnetic fields, these forces compound, creating pull that scales without linear effort.

Frequently asked questions

What is Electromagnetism?+

Electromagnetism is a mental model used for better thinking and decision-making.

How do you apply Electromagnetism?+

To apply Electromagnetism, identify situations where this framework is relevant, then use it as a lens to evaluate your options and decisions. The model is most useful when combined with other complementary mental models.

What category does Electromagnetism fall under?+

Electromagnetism falls under the Natural Sciences category of mental models. Other models in this category can be found on the Natural Sciences hub page.

Why is Electromagnetism important?+

Electromagnetism is important because it provides a structured way to think about problems that would otherwise be approached with intuition alone. Understanding this model helps you avoid common reasoning errors and make better decisions.
